# Coaxial Bore Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A model contains nested cylindrical features that must share one axis: bore, pocket, hub, sleeve, shaft clearance, bearing seat, pilot diameter, or counterbore.
|
||||
- The request mentions concentric, coaxial, central bore, shaft hole, bearing pocket, or flanged cylindrical geometry.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- Circular holes are independent mounting holes on a plate face.
|
||||
- The circular features intentionally use different centers.
|
||||
- The shape is decorative and has no functional axis.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Central bore or shaft clearance through a rotational or support body.
|
||||
- Concentric circles in sketch evidence.
|
||||
- Cylindrical faces nested around one axis.
|
||||
- Bearing seat, flange hub, sleeve, bushing, washer, spacer, or shaft-like part.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Use one explicit construction axis or shared sketch origin for all central cylindrical features.
|
||||
- Distinguish each diameter by role: clearance, seat, counterbore, outer diameter, pilot, groove.
|
||||
- Cut through holes through all relevant material; cut seats and counterbores only to their functional depth.
|
||||
- Do not create separate sketches whose centers can drift.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `axis` is the shared centerline.
|
||||
- `bore_diameter` controls the through opening.
|
||||
- `seat_diameter` controls bearing/pilot/counterbore fit.
|
||||
- `outer_diameter` controls surrounding material.
|
||||
- `depth` controls blind pocket, counterbore, or groove depth.
|
||||
- `lead_in_chamfer` controls assembly entry.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the shared axis using the sketch origin, construction line, or selected cylindrical face.
|
||||
2. Sketch concentric circles or a revolved profile from that axis.
|
||||
3. Cut the smallest through bore first when it establishes shaft clearance.
|
||||
4. Cut larger seats, pockets, or counterbores to controlled depth.
|
||||
5. Add grooves, chamfers, and fillets after the primary coaxial cuts are stable.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Off-axis bore because each circle was sketched from a different center.
|
||||
- Confusing through bore diameter with bearing seat diameter.
|
||||
- Cutting the bearing pocket through all and deleting the shoulder.
|
||||
- Treating unrelated bolt holes as coaxial features.
|
||||
|
||||
## Evidence summary
|
||||
|
||||
- Current library evidence: 50 reviewed SCAD58 flange and bearing-seat models.
|
||||
- Latest run evidence: accepted insights for central bore alignment, concentric circles, bearing seats, flanges, washers, bushings, and axisymmetric bodies.
|
||||
- Frequent operations in the latest run: Cut, RevCut, Revolution, Extrusion of concentric circles, Chamfer.

# Counterbored Hole Creation Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A fastener hole needs a cylindrical recess so a socket head, cap screw head, or flat seating surface sits flush or below the top face.
|
||||
- The request mentions counterbore, counterbored hole, socket head screw, cap screw, recessed screw head, or flat-bottom screw seat.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The screw head requires a conical countersink rather than a cylindrical counterbore.
|
||||
- The feature is a bearing pocket, large cylindrical recess, decorative ring, or simple through hole.
|
||||
- The part has no fastener-seat function.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Through hole plus larger coaxial shallow cylindrical recess.
|
||||
- HoleWzd evidence for counterbored screw holes.
|
||||
- Descriptions mention recessed screw heads, socket head screws, counterbore depth, or flush mounting.
|
||||
- Often appears on mounting plates, brackets, flanges, and covers.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Counterbore axis and through-hole axis are identical.
|
||||
- Counterbore diameter must be larger than through-hole diameter.
|
||||
- Counterbore depth must be enough for the screw head but not cut through the part unless requested.
|
||||
- Create the hole as one standard feature when possible to preserve fastener intent.
|
||||
- Pattern the complete counterbored hole feature when repeated.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `through_hole_diameter` defines screw clearance.
|
||||
- `counterbore_diameter` defines head clearance.
|
||||
- `counterbore_depth` defines head seating depth.
|
||||
- `fastener_size` defines standard screw selection.
|
||||
- `placement_point` defines hole center.
|
||||
- `end_condition` defines through, blind, or up-to-next behavior.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the mounting face where the screw head sits.
|
||||
2. Place the hole center from datums or pattern references.
|
||||
3. Create a counterbored hole feature with through diameter, counterbore diameter, and counterbore depth.
|
||||
4. Confirm the counterbore opens on the correct face.
|
||||
5. Pattern or mirror the full counterbored hole feature if repeated.
|
||||
6. Add small entrance chamfers only after the counterbore is correct.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Modeling only a shallow large circle without the through hole.
|
||||
- Reversing the counterbore to the wrong side of the part.
|
||||
- Making counterbore and through-hole diameters equal.
|
||||
- Using countersink geometry for a socket head screw.
|
||||
- Patterning only the through hole and forgetting the recess.
|
||||
|
||||
## Evidence summary
|
||||
|
||||
- Latest run evidence: 49 accepted atomic insights matched counterbored hole creation.
|
||||
- Strong repeated names include `create_counterbored_hole`, `use_hole_wizard_for_counterbored_holes`, and `create_counterbore_hole_for_socket_head_screw`.

# Extrude Base Profile Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The first solid body is a simple prismatic shape made from a closed 2D profile: rectangle, rounded rectangle, circle, annulus, hexagon, or simple contour.
|
||||
- The part is a plate, block, simple cylinder, bracket base, washer blank, spacer blank, or nut body made by extrusion.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The primary body has multiple coaxial diameter steps better made by revolve.
|
||||
- The shape is freeform, lofted, swept, bent sheet metal, or surface-based.
|
||||
- The extrusion profile is open or ambiguous.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- SolidWorks evidence such as Extrusion/Boss-Extrude after a single sketch.
|
||||
- STEP evidence dominated by planar faces for prismatic parts or cylindrical surfaces for simple cylinders.
|
||||
- Descriptions mention rectangular block, plate, simple cylinder, extruded profile, or uniform thickness.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Start from a fully closed, constrained sketch.
|
||||
- Extrude normal to the sketch plane by the intended thickness or length.
|
||||
- Use symmetric or mid-plane extrusion when the part should stay centered on a datum.
|
||||
- Keep the base body simple; add holes, pockets, bosses, slots, and edge treatments as later features.
|
||||
- Use concentric circles for annular extrusions such as washers or tubes.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `profile_type` selects rectangle, circle, annulus, hexagon, or custom closed contour.
|
||||
- `length`, `width`, `radius`, `outer_radius`, `inner_radius`, and `across_flats` define the sketch.
|
||||
- `extrude_depth` or `thickness` defines the solid depth.
|
||||
- `extrude_direction` and `midplane` define placement relative to datums.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the reference plane or face for the base profile.
|
||||
2. Draw and constrain the closed profile.
|
||||
3. Apply dimensional constraints for width, length, radius, or diameter.
|
||||
4. Extrude the profile to the required depth.
|
||||
5. Keep the resulting body merged as the main solid unless separate bodies are explicitly requested.
|
||||
6. Add secondary cuts and edge treatments afterward.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Using an open sketch for solid extrusion.
|
||||
- Combining holes and detailed cutouts into the first sketch when separate features would be clearer.
|
||||
- Using multiple separate extrusions for what should be one base body.
|
||||
- Extruding a stepped shaft when revolve would preserve axial intent better.
|
||||
|
||||
## Evidence summary
|
||||
|
||||
- Latest run evidence: 70 accepted atomic insights matched base extrusion from rectangular/circular profiles.
|
||||

# Fillet Chamfer Last Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A machined part needs edge breaks, deburring chamfers, assembly lead-ins, stress-relief fillets, or small finishing rounds.
|
||||
- The edge treatment is secondary to the main body, holes, pockets, slots, and bores.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The rounded or chamfered profile is the primary defining shape, such as an O-ring groove, cam surface, ergonomic shell, or turbine blade.
|
||||
- A sharp edge is explicitly required for sealing, locating, scraping, or mating.
|
||||
- The chamfer/fillet would remove critical wall thickness around a hole, shoulder, or thin rib.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- SolidWorks feature evidence such as Chamfer, Fillet, radius values, or angle-distance chamfers.
|
||||
- STEP evidence with conical or toroidal surfaces near final edges.
|
||||
- Descriptions mentioning chamfered edges, rounded corners, smooth transitions, edge relief, assembly ease, or stress reduction.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Apply edge treatments after primary solids, holes, bores, pockets, slots, and patterns are stable.
|
||||
- Keep edge treatment small relative to nearby feature size and wall thickness.
|
||||
- Use chamfer for lead-in/deburring and fillet for stress relief or smooth load transition.
|
||||
- Select specific edges; do not blindly fillet or chamfer every edge.
|
||||
- Preserve functional shoulders, datum faces, seal lands, and fastener seats.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `chamfer_distance` defines bevel size.
|
||||
- `chamfer_angle` defines bevel angle, often 45 degrees when not otherwise specified.
|
||||
- `fillet_radius` defines round size.
|
||||
- `edge_set` defines which edges receive treatment.
|
||||
- `minimum_wall_after_edge_treatment` protects small holes, ribs, and pockets.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Complete the main body and all functional cuts.
|
||||
2. Identify functional edges that need lead-in, deburring, stress relief, or handling safety.
|
||||
3. Apply chamfers to hole entrances, exposed outer edges, or insertion edges.
|
||||
4. Apply fillets to internal corners, web transitions, and load-bearing transitions.
|
||||
5. Verify that holes, slots, shoulders, and bearing seats remain intact.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Adding large fillets early and causing later cuts or patterns to fail.
|
||||
- Chamfering a bearing shoulder, seal land, or datum face that should remain crisp.
|
||||
- Using one global fillet radius across tiny holes and large outer edges.
|
||||
- Treating decorative edge rounding as more important than functional geometry.
|
||||
|
||||

# Pattern Holes From Datum Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A model has repeated holes or repeated cut features that should be controlled by pitch, angle, symmetry, or a construction datum.
|
||||
- The design intent is a hole row, hole grid, mirrored pair, circular bolt circle, or repeated mounting pattern.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- There is only one custom non-repeated hole.
|
||||
- Holes are intentionally irregular or individually dimensioned.
|
||||
- The feature is decorative and not constrained by functional layout.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Multiple holes with equal spacing, equal angular spacing, or mirrored positions.
|
||||
- SolidWorks evidence such as LinearPattern, CircularPattern, MirrorPattern, or repeated HoleWzd features.
|
||||
- Datum clues such as centerlines, edge offsets, pitch dimensions, central axis, or symmetry planes.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Build one correct seed hole or seed cut feature first.
|
||||
- Constrain the seed from a datum: edge offset, centerline, pitch circle, or axis.
|
||||
- Pattern the feature/cut, not only sketch circles.
|
||||
- Choose pattern type from geometry: linear for rows/grids, circular for flange bolt circles, mirror for symmetric pairs.
|
||||
- Keep the pattern editable by count, pitch, angle, and axis rather than hard-coded coordinates.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `seed_position` defines the first hole from the datum.
|
||||
- `pitch` defines linear spacing.
|
||||
- `count` defines number of repeated instances.
|
||||
- `pattern_direction` defines row/grid direction.
|
||||
- `pattern_axis` defines circular pattern axis.
|
||||
- `total_angle` is usually 360 degrees for full bolt circles.
|
||||
- `mirror_plane` defines symmetric duplication.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the datum: edge offset, centerline, symmetry plane, or central axis.
|
||||
2. Create and validate one seed hole or cut feature.
|
||||
3. Select linear, circular, or mirror pattern based on the part family and layout.
|
||||
4. Pattern the feature with explicit count and spacing/angle.
|
||||
5. Add shared counterbore/countersink/thread detail before patterning when all instances match.
|
||||
6. Verify clearance to edges, central bores, slots, and neighboring holes.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Duplicating sketch circles without actual cuts.
|
||||
- Using linear pattern for a flange bolt circle.
|
||||
- Using circular pattern for rectangular plate holes.
|
||||
- Patterning counterbore circles without patterning the underlying through hole.
|
||||
- Missing the datum so later size changes break alignment.
|
||||
|
||||

|
||||
|
||||
- Current library evidence: 58 reviewed SCAD58 models with repeated hole patterns.

# Revolve Profile Around Axis Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A single feature is created by revolving a 2D profile around an axis: stepped cylinder, shaft shoulder, sleeve, bushing, washer groove, nut blank, knob, or circular recess.
|
||||
- The feature has a rotational cross-section that is easier to define in side view.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- A plain constant-diameter cylinder can be created more simply by extruding a circle.
|
||||
- The profile is open, crosses the axis incorrectly, or represents non-axisymmetric geometry.
|
||||
- The feature is a rectangular plate, bracket wall, or arbitrary cutout.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Revolution/Revolve/RevCut feature evidence.
|
||||
- Sketch contains an axis line or construction centerline.
|
||||
- Multiple coaxial cylindrical, conical, or toroidal surfaces are expected.
|
||||
- Profile controls axial steps, shoulders, tapers, grooves, or rounded transitions.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- The revolve axis must be explicit and stable.
|
||||
- The profile must be closed for material-adding revolve.
|
||||
- Keep the profile on the correct side of the axis to avoid self-intersection.
|
||||
- Use 360 degrees for complete rotational solids unless a partial sector is requested.
|
||||
- Use revolved cut, not boss revolve, when removing a groove or internal recess.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `axis` defines the rotation center.
|
||||
- `profile` defines the closed side-view outline.
|
||||
- `revolve_angle` defines full or partial rotation.
|
||||
- `diameter_steps`, `axial_lengths`, `groove_depth`, and `taper_angle` define shape.
|
||||
- `operation_type` selects add or cut.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Create a sketch on a plane that contains the desired axis.
|
||||
2. Draw a construction axis or select a stable centerline.
|
||||
3. Draw the closed profile for added material, or the removal profile for a revolved cut.
|
||||
4. Revolve the profile around the axis, usually 360 degrees.
|
||||
5. Validate that the result is one solid and all intended circular features are coaxial.
|
||||
6. Add later holes, flats, slots, patterns, chamfers, and fillets as separate features.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Revolving around the wrong edge or temporary line.
|
||||
- Letting the sketch cross the axis and causing invalid geometry.
|
||||
- Making several extruded cylinders instead of a single coherent turned profile.
|
||||
- Using revolve for non-axisymmetric bracket or plate features.

# Threaded Hole Creation Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part needs an internal thread, tapped hole, threaded mounting hole, or screw hole with a specified metric/imperial size.
|
||||
- The request mentions M3, M4, M5, M6, M8, M10, tapped hole, threaded hole, or thread depth.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The feature is an external thread on a bolt, screw, or shaft.
|
||||
- The hole is only a smooth clearance hole.
|
||||
- The model should avoid thread geometry and only show a simple bore unless the prompt asks for thread detail.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- SolidWorks evidence such as HoleWzd threaded hole or thread parameters.
|
||||
- Descriptions mention fastening, tapped holes, internal thread, or screw mounting.
|
||||
- Hole is located on a planar face, boss face, or shaft end face.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Use a standard threaded hole feature or thread callout when available.
|
||||
- Keep the threaded hole axis normal to the placement face unless angled threading is requested.
|
||||
- Separate tap drill diameter, nominal thread size, hole depth, and thread depth.
|
||||
- Keep enough wall material around the threaded hole.
|
||||
- Add lead-in chamfer after the thread/hole is placed.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `thread_size` defines nominal size such as M3/M4/M5/M6/M8/M10.
|
||||
- `thread_pitch` defines fine/coarse pitch when specified.
|
||||
- `thread_depth` defines threaded length.
|
||||
- `hole_depth` defines blind hole depth if not through.
|
||||
- `placement_point` and `face_normal` define location and direction.
|
||||
- `lead_in_chamfer` defines assembly entry.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the planar face or end face for the threaded hole.
|
||||
2. Place the hole center from datums, centerlines, or axis references.
|
||||
3. Create the hole using a threaded HoleWzd/hole feature with size and depth.
|
||||
4. If the backend cannot model threads, create the correct pilot bore and preserve thread intent in naming/comments.
|
||||
5. Pattern or mirror the threaded hole feature when repeated.
|
||||
6. Add a small lead-in chamfer after the threaded feature is stable.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Modeling a threaded hole as a plain through cylinder.
|
||||
- Creating external thread geometry on an internal hole.
|
||||
- Placing threaded holes too close to edges, slots, or pockets.
|
||||
- Forgetting blind depth or thread depth.
|
||||
- Adding visual helical threads that make the model heavy or fragile when a callout is enough.
|
||||
|
||||
## Evidence summary
|
||||
|
||||
- Latest run evidence: 87 accepted atomic insights matched threaded/tapped hole creation.

# Through Hole Cut Atomic Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part needs a clean circular hole or bore that passes fully through a plate, block, bracket wall, flange, washer, spacer, or boss.
|
||||
- The request mentions through hole, clearance hole, central hole, circular opening, bore through, or cut through all.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The hole is threaded, counterbored, countersunk, or a bearing seat requiring special geometry.
|
||||
- The circular feature is a blind pocket, groove, decorative recess, or non-through relief.
|
||||
- The hole is part of a patterned bolt circle; combine with the pattern skill for repeated holes.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Circular sketch on a planar face followed by Cut-Extrude or HoleWzd through all.
|
||||
- Cylindrical internal face runs through the full thickness.
|
||||
- Used for clearance, alignment, lightening, shaft passage, or central opening.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Hole axis should be normal to the face or coaxial with the main part axis.
|
||||
- Use through-all end condition when the hole must pass through the entire body.
|
||||
- Keep hole diameter and placement explicit.
|
||||
- For central holes, use the part axis or centerline as the placement reference.
|
||||
- For repeated holes, make one seed through hole and pattern it.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `hole_diameter` defines opening size.
|
||||
- `placement_point` defines center on the start face.
|
||||
- `axis` defines coaxial central placement when needed.
|
||||
- `end_condition` is usually through all.
|
||||
- `face` defines the start plane.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the face or reference plane where the hole starts.
|
||||
2. Place a circle center from datums, centerlines, or the main axis.
|
||||
3. Sketch the circle with the required diameter.
|
||||
4. Cut through all material in the intended direction.
|
||||
5. Pattern or mirror the through-hole cut if repeated.
|
||||
6. Add hole edge chamfers only after the cut exists.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Creating a shallow blind pocket when a through hole is required.
|
||||
- Leaving a sketch circle without cutting material.
|
||||
- Placing a central hole off-axis.
|
||||
- Treating threaded/counterbored/bearing holes as plain through holes.
|
||||
- Cutting through unintended bodies in an assembly-like model.

# Axisymmetric Revolve Strategy Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part or major feature is rotationally symmetric around an axis: shaft, stepped shaft, flange hub, bushing, washer, spacer, sleeve, pulley-like blank, turned knob, or nut blank.
|
||||
- The profile contains steps, shoulders, grooves, tapers, spherical/rounded transitions, or coaxial bores that are easier to define in a half-section.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The body is a simple constant-diameter cylinder that can be created by one circle extrusion.
|
||||
- The part is primarily prismatic with only small cylindrical holes.
|
||||
- The geometry is freeform, non-axisymmetric, or has asymmetric lugs as the dominant feature.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Dominant central axis and circular cross-sections.
|
||||
- SolidWorks features such as Revolution, Revolve, RevCut, or revolved thread/groove cuts.
|
||||
- STEP evidence with multiple cylindrical, conical, or toroidal surfaces sharing an axis.
|
||||
- Functional roles include shafting, spacing, sealing, rotation, alignment, or fastening.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Sketch the axial cross-section on a plane that contains the rotation axis.
|
||||
- Keep the revolved profile on one side of the axis unless the CAD kernel expects a centerline profile.
|
||||
- Use one 360-degree revolve for the main axisymmetric body where possible.
|
||||
- Use revolved cuts for coaxial grooves, internal thread reliefs, and circular recesses.
|
||||
- Add asymmetric holes, flats, keyways, or bolt patterns after the revolved body is complete.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `axis` defines the rotation centerline.
|
||||
- `profile_points` define the half-section outline.
|
||||
- `diameters` and `axial_lengths` define steps and shoulders.
|
||||
- `revolve_angle` is usually 360 degrees for a complete solid.
|
||||
- `groove_width`, `groove_depth`, `taper_angle`, and `fillet_radius` define turned details.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the central axis and an axial sketch plane.
|
||||
2. Draw the half-section profile with all major diameters, steps, shoulders, and bore boundaries.
|
||||
3. Revolve the closed profile 360 degrees to create the main body.
|
||||
4. Use revolved cuts for grooves, recesses, or thread reliefs that are also axisymmetric.
|
||||
5. Add non-axisymmetric secondary features such as flats, slots, keyways, or bolt holes.
|
||||
6. Apply chamfers and fillets at ends and shoulders last.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Extruding several cylinders separately and leaving seams or separate bodies.
|
||||
- Revolving a profile that crosses the axis and creates invalid self-intersections.
|
||||
- Forgetting the construction axis or using an arbitrary edge as axis.
|
||||
- Adding asymmetric features before the revolve and making the base profile ambiguous.
|
||||
- Using revolve for a simple plain cylinder when extrusion is clearer.
|
||||

||||

# Bearing Bore Seat Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part must locate a bearing, bushing, sleeve, or shaft using a coaxial bore, counterbore, pocket, shoulder, or retaining seat.
|
||||
- The requested model is a housing/seat component, bracketed bearing support, bushing support, or bearing retainer.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The part only has generic decorative holes or a simple washer hole.
|
||||
- The task is to create a full bearing assembly with rolling elements.
|
||||
- The central hole is only a screw clearance hole and not a shaft/bearing datum.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Through bore for shaft clearance.
|
||||
- Larger coaxial pocket for bearing outside diameter.
|
||||
- Shoulder or depth stop for axial location.
|
||||
- Optional retaining groove, cover recess, set-screw hole, lubrication hole, or mounting base.
|
||||
- Bore entry chamfers for assembly.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Shaft clearance bore and bearing seat remain coaxial.
|
||||
- Seat diameter is larger than shaft clearance diameter when a bearing pocket is present.
|
||||
- Seat depth must be represented; a bearing seat is not just a surface ring.
|
||||
- Shoulder geometry should remain after the pocket cut.
|
||||
- Mounting holes must not break into the bearing seat unless explicitly designed.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `axis` defines the bore centerline.
|
||||
- `shaft_clearance_diameter` defines the through hole.
|
||||
- `bearing_outer_diameter` defines the pocket/seat diameter.
|
||||
- `seat_depth` defines bearing insertion depth.
|
||||
- `shoulder_diameter` and `shoulder_height` define axial stop.
|
||||
- `retaining_groove_width` and `retaining_groove_depth` define optional retention.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Create or select the main housing body.
|
||||
2. Establish a construction axis through the intended shaft centerline.
|
||||
3. Cut the shaft clearance bore through all relevant material.
|
||||
4. Cut the bearing seat/counterbore to controlled depth from the assembly side.
|
||||
5. Preserve or create the shoulder that stops the bearing.
|
||||
6. Add retaining grooves, set-screw holes, lubrication holes, and mounting holes only after the bore/seat is correct.
|
||||
7. Apply bore lead-in chamfers and small external fillets last.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Making the seat blind depth ambiguous.
|
||||
- Losing the shoulder by cutting the same diameter through the whole body.
|
||||
- Off-axis bearing pocket relative to shaft bore.
|
||||
- Treating bearing housing as complete bearing assembly.
|
||||
- Adding mounting holes before the seat and accidentally breaking the pocket wall.
|
||||
|
||||

# Flange Bolt Circle Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A flange, circular cover, annular ring, coupling, or flanged sleeve needs fastener holes evenly spaced around a central bore.
|
||||
- The request mentions bolt circle, pitch circle, PCD, evenly spaced flange holes, or circular pattern of screws.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- Holes are in a rectangular grid, linear row, or mirrored pair on a plate or bracket.
|
||||
- The part has no central axis or central bore.
|
||||
- The holes are decorative circular cutouts rather than fastening holes.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Central bore or hub defines the rotation axis.
|
||||
- Bolt holes lie on a pitch circle concentric with the bore.
|
||||
- Angular spacing is equal: `360 / bolt_count`.
|
||||
- Optional counterbores or countersinks remain concentric with each bolt hole.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Bolt-circle center, central bore, hub, and outer diameter share the same axis.
|
||||
- Create one correct seed hole with the correct diameter and seat type.
|
||||
- Circular-pattern the hole feature, not just sketch circles.
|
||||
- Keep bolt count, pitch-circle diameter, and start angle explicit.
|
||||
- Add counterbore/countersink to the seed hole before patterning when all holes share the same fastener type.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `bolt_count` controls number of fastener holes.
|
||||
- `bolt_circle_diameter` or `pitch_circle_diameter` controls radial placement.
|
||||
- `bolt_hole_diameter` defines clearance or pilot size.
|
||||
- `start_angle` controls angular orientation relative to a datum.
|
||||
- `counterbore_diameter`, `counterbore_depth`, and `countersink_angle` define fastener seating.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the central axis from the flange bore or construction geometry.
|
||||
2. Place one seed hole center at radius `bolt_circle_diameter / 2`.
|
||||
3. Create the seed hole as a cut, HoleWzd hole, counterbore, or countersink according to the fastener.
|
||||
4. Use circular pattern around the central axis for `bolt_count` instances over 360 degrees.
|
||||
5. Verify that every patterned hole cuts through the flange and remains inside the outer diameter.
|
||||
6. Add final chamfers and fillets after the bolt pattern is complete.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Manually placing each hole and producing uneven angular spacing.
|
||||
- Patterning a sketch without cutting material.
|
||||
- Using a linear array on a circular flange.
|
||||
- Choosing pitch circle too close to the bore or outer edge.
|
||||
- Forgetting counterbore/countersink depth for flush fasteners.

# Mounting Plate Hole Layout Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A plate or base block needs holes, slots, counterbores, countersinks, or threaded holes positioned from datum edges or centerlines.
|
||||
- The layout is rectangular, row-based, symmetric, mirrored, or grid-like rather than circular around a flange axis.
|
||||
- The hole layout controls mounting, alignment, adjustment, or fastening.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- Holes are evenly spaced around a circular bolt circle on a flange.
|
||||
- The holes are decorative, random, or not functionally related.
|
||||
- The main operation is a bearing bore or central shaft seat rather than a mounting-hole layout.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Flat planar top face or side face used as the hole placement plane.
|
||||
- Edge margins, centerline offsets, pitch values, or symmetric pairs.
|
||||
- Repeated hole groups, slots, threaded holes, clearance holes, counterbores, countersinks, or dowel holes.
|
||||
- SolidWorks evidence often appears as HoleWzd, Cut, LPattern, MirrorPattern, and Chamfer.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Define plate datums before hole placement.
|
||||
- Keep hole centers constrained to margins, pitch, and symmetry instead of free coordinates.
|
||||
- Select the hole type from fastening function, not from appearance.
|
||||
- Pattern the cut or hole feature after the seed feature is correct.
|
||||
- Preserve minimum material around holes and between holes.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `datum_edge_x`, `datum_edge_y`, and `centerline` define references.
|
||||
- `edge_margin_x`, `edge_margin_y`, `pitch_x`, `pitch_y`, `row_count`, and `column_count` define repeated layouts.
|
||||
- `hole_diameter`, `thread_size`, `fit`, and `end_condition` define the hole itself.
|
||||
- `counterbore_diameter`, `counterbore_depth`, `countersink_angle`, and `slot_length` define fastener seating or adjustability.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the plate face and define construction centerlines or edge-offset dimensions.
|
||||
2. Create one seed hole or one seed hole group using HoleWzd or a through cut.
|
||||
3. Use linear pattern for rows/grids and mirror for symmetric pairs.
|
||||
4. Use slots when the design requires adjustment rather than fixed bolt location.
|
||||
5. Add counterbore, countersink, or thread data to the seed hole before patterning where possible.
|
||||
6. Add chamfers and deburring features after the functional holes are complete.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Converting counterbored/threaded/countersunk holes into plain cylinders.
|
||||
- Patterning sketch circles instead of the actual cut or hole feature.
|
||||
- Mixing flange bolt-circle logic into rectangular plate layouts.
|
||||
- Missing datum margins, causing holes to float.
|
||||
- Placing slots too close to edges or other holes.
|
||||

||||

# Slotted Adjustment Feature Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A plate, bracket, clamp, guide, or mounting part needs an elongated slot for positional adjustment, clearance, sliding, or alignment.
|
||||
- The request mentions slot, slotted hole, adjustment slot, elongated hole, guide slot, keyway-like slot, or obround cutout.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The feature is a simple round hole with no adjustment function.
|
||||
- The slot is actually a shaft keyway or turned groove; use a shaft/keyway-specific rule if available.
|
||||
- The slot is decorative and not tied to fastening, travel, or clearance.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Elongated hole with two semicircular ends and straight sides.
|
||||
- Slot located on a flat plate/bracket face or through a wall.
|
||||
- Often paired, mirrored, or patterned.
|
||||
- Can coexist with counterbored holes, threaded holes, ribs, or edge chamfers.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Slot width should match the fastener/shaft clearance role.
|
||||
- Slot length defines adjustment travel and must be longer than the fastener diameter.
|
||||
- Keep end radii equal to half the slot width for manufacturable milled/slot features.
|
||||
- Dimension slots from datums and centerlines.
|
||||
- Cut slots after the base body exists and before final chamfers/fillets.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `slot_width` defines cutter or fastener clearance.
|
||||
- `slot_length` defines adjustment range.
|
||||
- `end_radius` is usually `slot_width / 2`.
|
||||
- `slot_center`, `slot_angle`, and `edge_margin` locate the slot.
|
||||
- `slot_depth` or `through_all` defines end condition.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the planar face or reference plane where the slot starts.
|
||||
2. Sketch an obround slot from centerline, length, and width.
|
||||
3. Cut through all or to the required depth.
|
||||
4. Pattern or mirror the slot if repeated.
|
||||
5. Add small chamfers to slot edges after the cut is complete.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Modeling a slot as a rectangle with sharp internal corners.
|
||||
- Making the slot length equal to the hole diameter, removing adjustment function.
|
||||
- Placing slots without enough wall material at the ends.
|
||||
- Confusing a bracket adjustment slot with a shaft keyway or revolved groove.
|
||||
|
||||

# Standard Hole Wizard Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part needs standard clearance holes, threaded/tapped holes, counterbored holes, countersunk holes, dowel holes, or screw-seat holes.
|
||||
- The request mentions screw size, metric thread, socket head screw, flat head screw, fastener clearance, tapping, counterbore, countersink, or Hole Wizard-like behavior.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The circular feature is a bearing bore, shaft bore, decorative opening, large window, or non-standard milled pocket.
|
||||
- The hole is part of a freeform surface where a standard hole feature cannot be cleanly placed.
|
||||
- The user asks for detailed thread geometry and the CAD backend cannot represent it reliably.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Feature evidence such as HoleWzd, threaded hole, counterbored hole, countersunk hole, through hole, or standard metric sizes like M3, M4, M5, M6, M8, M10.
|
||||
- Holes are used for fastening, alignment, or assembly rather than decoration.
|
||||
- Hole positions are points on a planar face, often patterned or mirrored.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Select hole type before modeling: clearance, threaded, counterbore, countersink, or dowel.
|
||||
- Keep hole axis normal to the placement face unless an angled hole is explicitly requested.
|
||||
- Specify end condition: through all, blind depth, up to next, or thread depth.
|
||||
- Preserve fastener seating geometry: counterbore/countersink is not a decorative ring.
|
||||
- Pattern or mirror the completed hole feature when identical holes repeat.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `hole_type` selects clearance, threaded, counterbore, countersink, dowel, or simple through hole.
|
||||
- `standard` and `thread_size` define metric/imperial thread family when available.
|
||||
- `hole_diameter`, `tap_drill_diameter`, `thread_depth`, and `hole_depth` define cut size.
|
||||
- `counterbore_diameter`, `counterbore_depth`, and `countersink_angle` define screw head seating.
|
||||
- `placement_points`, `edge_offsets`, and `pattern_count` define layout.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Identify the fastening or alignment function for each hole group.
|
||||
2. Choose the matching standard hole type and size.
|
||||
3. Place hole center points on the correct face using datums, centerlines, or coordinates.
|
||||
4. Create the hole feature with diameter, depth, thread, and seating data.
|
||||
5. Pattern or mirror the completed hole feature when the group repeats.
|
||||
6. Add entrance chamfers only after the hole geometry is correct.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Modeling all holes as plain cylinders and losing thread/counterbore/countersink meaning.
|
||||
- Adding visual thread helixes where a thread callout or standard threaded hole is enough.
|
||||
- Forgetting counterbore depth for socket head screws.
|
||||
- Patterning hole center sketches without patterning the hole cut.
|
||||
- Using non-standard sizes when the prompt specifies standard fasteners.
|
||||
|
||||

# Symmetric Feature Layout Functional Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- A part has holes, cutouts, bosses, tabs, ribs, or slots arranged symmetrically about a centerline, midplane, or axis.
|
||||
- The prompt mentions symmetric holes, mirrored features, balanced mounting, centered layout, equal offsets, or left/right duplicates.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- Features are intentionally asymmetric for clearance, indexing, handedness, or mating orientation.
|
||||
- The only symmetry is the natural circular symmetry of a plain shaft or washer with no repeated secondary features.
|
||||
- The model requires unique hand-placed features with different sizes.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Hole pairs, mirrored slots, duplicated bosses, matching tabs, or opposite-side cutouts.
|
||||
- SolidWorks features such as MirrorPattern or sketches with construction centerlines.
|
||||
- Descriptions mention symmetry, balanced fastening, alignment, centered holes, or mirrored geometry.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Define the symmetry plane, centerline, or axis before placing the seed feature.
|
||||
- Model one side or one quadrant carefully, then mirror/pattern it.
|
||||
- Keep symmetric features tied to the same dimensions so edits preserve balance.
|
||||
- Do not mirror features that are explicitly handed or direction-specific.
|
||||
- Combine with hole-type rules when mirrored features are fastener holes.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `symmetry_plane` or `centerline` defines the mirror reference.
|
||||
- `seed_feature` defines the original hole, slot, boss, or cutout.
|
||||
- `offset_from_center`, `edge_margin`, and `pitch` define placement.
|
||||
- `mirror_count`, `pattern_count`, and `quadrant_count` define repetition intent.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Identify the natural datum: plate centerline, bracket midplane, flange axis, or body midplane.
|
||||
2. Create construction geometry for the symmetry reference.
|
||||
3. Build the seed feature on one side with full dimensions.
|
||||
4. Mirror or pattern the completed feature across the reference.
|
||||
5. Verify that all mirrored features remain inside material and keep correct hole type/depth.
|
||||
6. Apply common edge treatments after mirrored features are complete.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Manually placing mirrored holes and getting unequal offsets.
|
||||
- Mirroring asymmetric features such as countersinks that should face a specific side.
|
||||
- Losing thread/counterbore data during mirror or pattern.
|
||||
- Creating a visually symmetric model with unconstrained feature positions.
|
||||
|
||||

# Bearing Housing Or Seat Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a bearing housing, bearing seat, bearing support, bearing block, pillow-block-like support, bushing seat, shaft support, or retainer body.
|
||||
- The central functional feature is a precise coaxial bore, pocket, sleeve, shoulder, or counterbore that locates a bearing or bushing.
|
||||
- The part is a single machined component that supports a shaft or bearing, not the rolling bearing assembly itself.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The user asks for a complete bearing with balls, rollers, cage, inner race, and outer race.
|
||||
- The bearing word is only speculative and there is no bore, seat, sleeve, pocket, or retaining geometry.
|
||||
- The part is mainly a flange, washer, simple tube, or rectangular plate with unrelated holes.
|
||||
- The task requires an assembly of shaft, bearing, seals, fasteners, and housing together.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Coaxial shaft clearance bore through the body.
|
||||
- Larger bearing pocket or counterbore with controlled depth.
|
||||
- Shoulder, step, retaining lip, snap-ring groove, or cover seat to locate the bearing axially.
|
||||
- Mounting base, side lugs, flange, bolt holes, ribs, or bosses can appear, but they support the bearing axis rather than define the part family.
|
||||
- Chamfers at bore entrances and seat edges guide assembly.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Bearing seat diameter, shaft clearance diameter, housing outside diameter, and cover features share one axis.
|
||||
- Separate the bearing outer-diameter seat from the shaft clearance bore; they are not the same feature.
|
||||
- Leave a shoulder or defined depth when the bearing must stop axially.
|
||||
- Build enough housing material before cutting the bearing pocket.
|
||||
- Add mounting holes and ribs after the main bore/seat relationship is established.
|
||||
- Do not model balls or rollers unless the prompt explicitly asks for a bearing assembly.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `bearing_outer_diameter` defines the pocket or seat diameter.
|
||||
- `shaft_clearance_diameter` defines the through bore.
|
||||
- `seat_depth` defines how far the bearing is inserted.
|
||||
- `shoulder_height` or `shoulder_diameter` defines axial retention.
|
||||
- `housing_wall_thickness` controls material around the bearing pocket.
|
||||
- `mounting_hole_pattern`, `base_length`, `base_width`, and `base_thickness` define attachment to the frame.
|
||||
- `rib_thickness` and `rib_height` define optional support ribs.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the bearing axis and choose the housing form: block, flanged seat, sleeve, pedestal, or bracketed support.
|
||||
2. Create the main housing/body with enough wall thickness around the bearing axis.
|
||||
3. Cut the through shaft clearance bore on the main axis.
|
||||
4. Cut the bearing pocket/counterbore to its seat depth, leaving a clear shoulder where needed.
|
||||
5. Add retaining grooves, cover recesses, set-screw holes, oil holes, or alignment features only if requested.
|
||||
6. Add base mounting holes, bolt pads, ribs, and bosses using datum-driven positions.
|
||||
7. Finish with bore lead-in chamfers, outside chamfers, and small fillets.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Generating a bearing assembly instead of a housing or seat part.
|
||||
- Making the bearing seat and shaft clearance the same diameter.
|
||||
- Missing the shoulder/depth that locates the bearing.
|
||||
- Off-axis mounting of bore, pocket, or outer sleeve.
|
||||
- Turning every bearing support into a flange even when the evidence suggests a block or pedestal.
|
||||
- Adding decorative ribs or fasteners that obscure the bearing pocket.
|
||||

# Flange Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a circular flange, coupling flange, pipe flange, gasket-like flange, flanged sleeve, or flanged cylindrical adapter.
|
||||
- The part has a central axis, central bore, and fastener holes arranged around a pitch circle.
|
||||
- The flange connects, spaces, seals, or mounts coaxial parts such as shafts, pipes, bearings, covers, or couplings.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The word flange only means a side tab, flat ear, or rectangular mounting plate extension.
|
||||
- The hole layout is a rectangular grid, edge row, or arbitrary plate pattern.
|
||||
- The model is primarily a plain shaft, washer, pulley, bearing assembly, or bracket without a true circular flange body.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Axisymmetric disc, annular ring, raised hub, sleeve, stepped boss, or cylindrical landing surface.
|
||||
- Central through bore, pilot bore, counterbore, recess, seal land, or shaft clearance on the main axis.
|
||||
- Bolt holes are evenly spaced by angle around the same center as the bore.
|
||||
- Optional recesses, gasket grooves, chamfers, fillets, or counterbores are secondary to the coaxial flange body.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- The outer diameter, bore, hub, sleeve, recesses, and bolt circle share one central construction axis.
|
||||
- Build the rotational body before cutting the bolt holes.
|
||||
- Define bolt-circle diameter separately from outer diameter and bore diameter.
|
||||
- Create one correct bolt hole, then circular-pattern the cut feature over 360 degrees.
|
||||
- Do not replace the bolt circle with a rectangular hole grid.
|
||||
- Keep fillets, chamfers, and cosmetic edge breaks late in the sequence.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `outer_diameter` defines the flange envelope.
|
||||
- `thickness` defines the disc or flange plate depth.
|
||||
- `bore_diameter` defines shaft or pipe clearance.
|
||||
- `hub_diameter`, `hub_height`, and `pilot_diameter` define raised coaxial features.
|
||||
- `bolt_circle_diameter`, `bolt_count`, `bolt_hole_diameter`, and `start_angle` define the fastener pattern.
|
||||
- `counterbore_diameter`, `counterbore_depth`, `gasket_groove_width`, and `gasket_groove_depth` define secondary seats.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Establish the central axis and primary reference plane.
|
||||
2. Create the flange disc and any coaxial hub or sleeve using revolve for stepped profiles, or extrude circles for simple flat discs.
|
||||
3. Cut the central bore through the flange and hub on the same axis.
|
||||
4. Add one bolt hole at the pitch radius using the correct fastener hole type.
|
||||
5. Circular-pattern that cut around the central axis with equal angular spacing.
|
||||
6. Add recesses, gasket grooves, counterbores, chamfers, and fillets after the bore and bolt pattern are stable.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Off-axis bore relative to hub or outer diameter.
|
||||
- Manual bolt hole placement that produces unequal angular spacing.
|
||||
- Confusing a rectangular mounting plate with a flange because both have multiple holes.
|
||||
- Forgetting the central bore and creating only a circular plate with holes.
|
||||
- Applying large fillets before the bolt pattern and causing feature failure.
|
||||
|
||||
## Evidence summary
|
||||
|
||||
- Current library evidence: 45 previously reviewed SCAD58 flange-like models.
|
||||
- Latest run evidence: accepted insights for circular flange bolt holes, circular pattern around a central bore, revolved axisymmetric bodies, and coaxial cylindrical features.

# Hexagonal Nut Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a hex nut, hexagonal nut, machined nut, nut-like fastener, or hexagonal threaded insert.
|
||||
- The key features are wrench flats, a central threaded bore, and chamfered faces/edges.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The part is a bolt, screw, socket head cap screw, threaded rod, wing nut, cap nut, or flange nut unless the prompt explicitly asks for that variant.
|
||||
- The hexagon is only a decorative grip on another part.
|
||||
- The threaded feature is external rather than an internal bore.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Six flat wrench faces or hexagonal prism envelope.
|
||||
- Central internal threaded hole coaxial with the nut thickness.
|
||||
- Chamfers on top and bottom openings and on hex edges.
|
||||
- Optional counterbore, lead-in chamfer, or relieved thread entry.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Keep the threaded bore centered through the hex body.
|
||||
- Preserve the hex across-flats size separately from thread size and thickness.
|
||||
- Model chamfers as functional lead-ins and edge breaks, not as random bevels.
|
||||
- Represent internal thread intent using a threaded hole, thread callout, or helical/revolved cut only when required by output format.
|
||||
- Do not generate the mating bolt unless requested.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `across_flats` defines wrench size.
|
||||
- `thickness` defines nut height.
|
||||
- `thread_size`, `thread_diameter`, and `thread_depth` define the central bore.
|
||||
- `bore_diameter` defines the pre-thread or clearance hole if thread geometry is abstracted.
|
||||
- `face_chamfer` and `edge_chamfer` define lead-in and deburring.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Create the hexagonal body as a hex extrusion or by cutting flats from a revolved/chamfered blank.
|
||||
2. Define the central axis through the nut.
|
||||
3. Create the central bore or threaded hole through the body.
|
||||
4. Add thread representation or thread callout if the CAD output supports it.
|
||||
5. Add top/bottom lead-in chamfers and small edge chamfers.
|
||||
6. Verify the hex flats remain planar and the bore remains coaxial.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Producing a bolt or screw instead of a nut.
|
||||
- Forgetting the central threaded bore.
|
||||
- Placing the bore off-center relative to the hex body.
|
||||
- Making the chamfers so large that wrench flats disappear.
|
||||
- Treating a flange nut, cap nut, or wing nut as a plain hex nut.
|
||||
|
||||

||||
|
||||

# Mounting Bracket Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a mounting bracket, L bracket, U bracket, T bracket, support bracket, clamp bracket, lugged bracket, or machined support with holes.
|
||||
- The part has a load-bearing base plus one or more raised webs, tabs, arms, bosses, lugs, pockets, slots, or cutouts.
|
||||
- The model is a single machined bracket component, not an assembly with screws or attached hardware.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The part is only a flat plate with holes and no bracket-like 3D support structure.
|
||||
- The part is mainly a shaft, flange, bearing housing, complete hinge assembly, or sheet-metal bent bracket.
|
||||
- The prompt asks for a decorative stand or enclosure rather than a functional machined support.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Base block or plate that mounts to another part.
|
||||
- Vertical web, side wall, lug, tab, raised boss, or protruding arm.
|
||||
- Mounting holes, threaded holes, counterbores, slots, or cutouts.
|
||||
- Reinforcing ribs or fillets at transitions may appear when strength matters.
|
||||
- Hole placement is usually datum-driven and often symmetric or mirrored.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Build the main load path first: base, web/tab/lug, and boss geometry before small holes.
|
||||
- Keep bracket features as one coherent body unless the prompt explicitly asks for assembled parts.
|
||||
- Place holes from functional datums, not visual guesses.
|
||||
- Use standard hole features for threaded, counterbored, countersunk, and clearance holes.
|
||||
- Add cutouts/slots for clearance or adjustment only where they make functional sense.
|
||||
- Apply fillets/chamfers late, especially at web-to-base transitions and exposed edges.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `base_length`, `base_width`, and `base_thickness` define the mounting base.
|
||||
- `web_height`, `web_thickness`, `tab_width`, `lug_radius`, and `boss_diameter` define support geometry.
|
||||
- `hole_diameter`, `thread_size`, `counterbore_diameter`, and `slot_length` define fastening and adjustment.
|
||||
- `edge_margin`, `hole_pitch`, `symmetry_plane`, and `boss_offset` define layout.
|
||||
- `fillet_radius` controls stress relief at transitions.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Create the base extrusion or main bracket profile.
|
||||
2. Add vertical webs, tabs, lugs, bosses, or arms as secondary extrusions from clear datum faces.
|
||||
3. Cut clearance pockets, U/L/T-shaped openings, slots, or lightening cutouts.
|
||||
4. Add standard holes using HoleWzd or cut features, positioned from datums and symmetry references.
|
||||
5. Pattern or mirror repeated holes/features when the design is symmetric.
|
||||
6. Add structural fillets at web/base intersections, then finish with small chamfers on exposed edges.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Collapsing a bracket into a simple flat plate and losing the vertical/web structure.
|
||||
- Creating an assembly of screws, pins, or attached parts when only the bracket is requested.
|
||||
- Adding holes before the base/web geometry and producing floating or misaligned holes.
|
||||
- Mixing several unrelated bracket variants into one overloaded model.
|
||||
- Using decorative cutouts that weaken the load path or overlap holes.
|
||||
|
||||

# Mounting Plate Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a flat mounting plate, base plate, adapter plate, panel, fixture plate, or spacer plate.
|
||||
- The dominant body is a prismatic plate with functional holes, slots, counterbores, countersinks, threaded holes, pockets, or a central clearance cutout.
|
||||
- The plate locates, fastens, spaces, or supports other components from planar datum faces.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The primary geometry is an axisymmetric flange with a circular bolt pitch pattern.
|
||||
- The plate is only a secondary base under a bearing housing, bracket, motor body, or cylindrical module.
|
||||
- The part is a true 3D bracket with vertical webs, lugs, arms, or side walls that control the design.
|
||||
- The request is for sheet-metal bends, formed panels, or decorative flat art rather than a machined plate.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Rectangular, square, rounded-rectangle, or simple profile plate with mostly uniform thickness.
|
||||
- Holes are located from datum edges, centerlines, or symmetric offsets instead of arbitrary visual placement.
|
||||
- Common hole types include clearance holes, threaded holes, counterbored holes, countersunk holes, dowel holes, and through holes.
|
||||
- Cutouts can be central circular holes, rectangular windows, slots, pockets, or weight-reduction openings.
|
||||
- Edge chamfers and small fillets are usually finishing operations, not the defining shape.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Establish the base plate envelope, thickness, top face, bottom face, and edge datum references before adding holes.
|
||||
- Keep mounting holes fully constrained by edge margins, centerlines, pitch, symmetry, or functional datums.
|
||||
- Model holes as real cuts or standard hole features; do not leave sketch circles on the face.
|
||||
- Use one seed hole or hole group plus pattern/mirror when the layout is regular.
|
||||
- Choose hole type from function: clearance for bolts, threaded/tapped for fastening into the plate, counterbore/countersink for flush screw heads, slot for adjustment.
|
||||
- Apply chamfers and fillets after functional holes and cutouts so edge treatment does not distort hole geometry.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `length`, `width`, and `thickness` define the blank.
|
||||
- `corner_radius` or `corner_chamfer` controls perimeter treatment when requested.
|
||||
- `edge_margin_x`, `edge_margin_y`, `pitch_x`, and `pitch_y` locate rectangular hole groups.
|
||||
- `central_cutout_width`, `central_cutout_length`, or `central_bore_diameter` define clearance openings.
|
||||
- `hole_diameter`, `thread_size`, `counterbore_diameter`, `counterbore_depth`, `countersink_angle`, and `slot_length` define fastener features.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Create a constrained base sketch for the plate outline and extrude it to thickness.
|
||||
2. Define datum centerlines, edge offsets, and symmetry references on the main face.
|
||||
3. Add the central clearance hole, rectangular cutout, or pocket if it controls component clearance.
|
||||
4. Add the first functional hole using the correct hole type and end condition.
|
||||
5. Replicate regular hole groups with linear pattern, circular pattern, or mirror according to layout intent.
|
||||
6. Add slots, secondary pockets, bosses, or local relief cuts only after primary mounting references are stable.
|
||||
7. Finish with perimeter chamfers, small fillets, and deburring details.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Treating every round mark as the same generic hole and losing counterbore/thread/countersink meaning.
|
||||
- Placing holes by eyeballing coordinates instead of datum margins and symmetry.
|
||||
- Using a flange bolt-circle pattern for a rectangular plate grid.
|
||||
- Adding chamfers before holes, causing holes or counterbores to be clipped.
|
||||
- Over-modeling decorative bevels while missing the functional fastening layout.
|
||||
- Combining unrelated bracket walls or cylindrical housings into the mounting plate body.
|
||||

# Simple Shaft Or Cylindrical Rod Planning Skill
|
||||
|
||||
## When to use
|
||||
|
||||
- The request describes a single cylindrical rod, simple shaft, spacer rod, cylindrical pin, standoff-like cylinder, or shaft-like machined part.
|
||||
- The body is primarily a cylinder along one axis, optionally with end holes, chamfers, simple steps, flats, slots, or threaded holes.
|
||||
- The task is to generate one part, not a spindle cartridge or shaft assembly.
|
||||
|
||||
## Do not use when
|
||||
|
||||
- The request describes a spindle module, motor rotor assembly, gearbox shaft assembly, bearings, seals, pulleys, keys, and fasteners together.
|
||||
- The part is mainly a flange, washer, bushing, screw, bolt, or complex housing.
|
||||
- The body is a hollow tube or bearing sleeve where inner/outer diameter relationship is the main design intent.
|
||||
|
||||
## Recognition features
|
||||
|
||||
- Long cylindrical body with uniform or stepped diameters.
|
||||
- Central axis is the dominant datum.
|
||||
- Optional end chamfers, end fillets, centered threaded holes, transverse holes, flats, slots, grooves, or keyway-like cuts.
|
||||
- Turning and cylindrical surfaces dominate; milling may appear for flats, slots, or keyways.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- Establish one main shaft axis and overall length first.
|
||||
- Use extrude for a uniform simple cylinder; use revolve for stepped diameters, grooves, shoulders, tapers, or turned profiles.
|
||||
- Keep all coaxial diameter changes, end holes, and grooves aligned to the shaft axis.
|
||||
- Treat holes, slots, flats, keyways, and threads as secondary features.
|
||||
- Do not invent bearings, couplings, gears, or housings unless requested.
|
||||
|
||||
## Parameter roles
|
||||
|
||||
- `length` defines the axial span.
|
||||
- `diameter` defines a simple rod.
|
||||
- `step_diameters`, `step_lengths`, `shoulder_positions`, and `groove_width` define turned features.
|
||||
- `end_hole_diameter`, `thread_size`, and `thread_depth` define centered end holes.
|
||||
- `flat_width`, `slot_width`, `slot_depth`, and `keyway_length` define milled secondary features.
|
||||
- `chamfer_distance` and `fillet_radius` define edge finishing.
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Define the shaft axis and overall length.
|
||||
2. For a simple rod, sketch a circle and extrude along the axis.
|
||||
3. For stepped or shouldered shafts, sketch the half-profile and revolve it around the axis.
|
||||
4. Add centered end holes, threaded holes, grooves, flats, slots, or keyways as secondary cuts.
|
||||
5. Keep secondary features referenced to the shaft axis or end-face datums.
|
||||
6. Finish with end chamfers, shoulder fillets, and small edge breaks.
|
||||
|
||||
## Common failures
|
||||
|
||||
- Generating a spindle or bearing assembly when only a shaft/rod part was requested.
|
||||
- Creating off-axis end holes.
|
||||
- Using multiple separate bodies for diameter steps instead of one coherent solid.
|
||||
- Treating a threaded shaft, bolt, or screw as the same as a plain shaft without preserving thread/head differences.
|
||||
- Adding arbitrary decorative grooves that were not requested.
|
||||
|
||||
## Evidence summary
|
||||
|
||||

# CNC 常加工零件 references-only 优化调研与实施计划
|
||||
|
||||
本文档用于规划如何只通过 `references` 强化 `text-to-cad` 对常见 CNC 加工零件的生成质量。这里不新增 factory、validator、router 或专用生成器，只给 CAD agent 在写 build123d 代码前可阅读的建模知识：如何识别零件类型、该类零件的稳定结构特征、哪些参数必须显式命名、推荐建模顺序、常见失败模式，以及适合做 references-only 优化的实施方案。
|
||||
|
||||
结论先说清楚：references 是软约束，只能提高平均生成质量，不能保证工程正确性。凡是强依赖标准、曲线、产品负形、流体/气动/热管理、法规或精密公差的代表件，references 可以帮助生成“看起来像”的简化模型，但不适合作为可靠优化对象。
|
||||
|
||||
## 资料依据
|
||||
|
||||
本计划参考了公开 CNC 设计指南、典型零件结构介绍和行业加工资料，包括 Protolabs 与 Xometry 的 CNC 设计建议、法兰结构资料、轴承座/带座轴承资料、丝杠/花键/同步带轮资料、箱体/泵体/叶轮/螺旋桨/模具/夹具等制造资料。文末列出链接。资料只用于总结结构特征和建模指导，不等同于标准件规范、强度校核、流体性能、密封性能、医疗/航空合规或可加工性承诺。
|
||||
|
||||
## references-only 优化原则
|
||||
|
||||
每个 reference 文件建议按下面结构写：
|
||||
|
||||
1. 识别词：中文、英文、别名、相邻概念。
|
||||
2. 结构不变量：生成结果要像这个零件时必须具备的结构。
|
||||
3. 常见变体：避免把所有提示词压成一个模板。
|
||||
4. 默认策略：用户没有明确变体时生成什么。
|
||||
5. 参数角色：必须变成命名参数的尺寸。
|
||||
6. feature roles：建模计划里必须显式出现的功能结构。
|
||||
7. 建模顺序：更稳的 build123d 构造顺序。
|
||||
8. 常见失败：reference 要主动提醒模型避免什么。
|
||||
9. 检查目标：人工或通用 inspect 能看的几何事实。
|
||||
|
||||
写法上要多用“默认”“通常”“除非用户指定”，少用“必须永远生成某一种”。这样可以提升质量，同时保留多样性。
|
||||
|
||||
## 通用 CNC 建模规则
|
||||
|
||||
- 功能尺寸必须命名参数化，不要散落魔法数字。
|
||||
- 原点和坐标轴应跟主功能基准一致：轴线、中心孔、安装面、分型面、密封面、定位面等。
|
||||
- 先做基础实体，再做主孔/主腔/主轴线特征，再做次级孔槽口袋，最后倒角/圆角。
|
||||
- 用户没有指定时，孔、槽、台阶、壁厚要取保守可加工的比例，避免深窄槽、薄壁、尖锐内角和无意义微小特征。
|
||||
- 盘套类、轴类优先保证同轴；板类优先保证孔位和边距；箱体类优先保证安装面、壁厚、孔轴线和腔体关系。
|
||||
- 不要从 reference 推断真实公差、疲劳强度、密封性能、转子动平衡、医疗合规、航空适航等。
|
||||
|
||||
## 建议落地方式
|
||||
|
||||
第一阶段不要为每个代表件都建独立文件。建议先建 7 个 family reference：
|
||||
|
||||
- `references/part-families/shaft.md`
|
||||
- `references/part-families/disc-sleeve.md`
|
||||
- `references/part-families/housing.md`
|
||||
- `references/part-families/plate.md`
|
||||
- `references/part-families/freeform-surface.md`
|
||||
- `references/part-families/mold-tooling.md`
|
||||
- `references/part-families/precision-fixture.md`
|
||||
|
||||
如果后续 A/B 对比发现 broad family 不够，再拆出高价值专用文件，例如 `flange.md`、`bearing-housing.md`、`stepped-shaft.md`、`mounting-plate.md`、`timing-pulley.md`。
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
适合简化 references-only 优化。

|
||||
|
||||

|
||||
|
||||

|
||||
- 常见失败：没有定义输入/输出轴；轴线关系混乱；缺盖板；没有安装方式。
|
||||
|
||||
### 发动机缸体/缸盖
|
||||
|
||||
不适合作为 references-only 优化对象。
|
||||
|
||||
原因：真实缸体/缸盖强依赖缸数和缸径、燃烧室、气门机构、水套、油道、缸垫孔型、铸造与加工工艺、强度和热管理。reference 可以生成教学级简化块体，但不能可靠优化“发动机缸体/缸盖”这类工业零件。因此不写实施计划。
|
||||
|
||||
### 泵体
|
||||
|
||||
只适合简化 references-only 优化；不适合流体性能或真实水力设计。
|
||||

|
||||
- 常见失败：普通盒子打孔；没有叶轮腔；入口出口不连通；缺密封面。
|
||||
|
||||
## 4. 板类零件
|
||||
|
||||
代表件：安装底板、连接板、模板、面板。
|
||||
|
||||

- 重点是厚度、外形、孔阵列、槽、沉孔/沉头、螺纹孔、基准边、倒角。
|
||||
|
||||
### 安装底板
|
||||
|
||||
高度适合 references-only 优化。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`安装底板`、`mounting plate`、`base plate`。
|
||||
- 不变量：平板实体；安装孔；厚度；基准边或中心线。

|
||||
高度适合 references-only 优化。
|
||||
|

|
||||
- 常见失败：把两个孔型合成一个；丢失偏置关系；孔位不对称。
|
||||
|
||||
### 模板
|
||||
|
||||
在几何明确时适合 references-only 优化；自由曲线模板需要尺寸或参考图。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`模板`、`drill template`、`routing template`、`inspection template`。

|
||||
- 建模顺序：面板主体；切主开口；切小孔/槽；倒角去毛刺。

|
||||
|
||||
## 5. 异形件/曲面零件
|
||||
|
||||
代表件：叶轮、涡轮叶片、螺旋桨、凸轮。
|
||||
|
||||
共同判断：这类零件往往需要曲线、扭转、截面分布、运动规律或气动/流体设计。references-only 可以指导简化外形，但很难保证真实工程正确。
|
||||
|
||||
### 叶轮
|
||||
|
||||
适合简化 references-only 优化；不适合水力/气动性能。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`叶轮`、`impeller`、`centrifugal impeller`、`compressor wheel`。
|
||||
- 不变量：中心轮毂；中心孔；背板或盖板；重复叶片；绕轴对称。
|
||||

|
||||
- 默认：开式离心叶轮，背板、轮毂、中心孔、均布后弯叶片。
|
||||
- 参数角色：`outer_diameter`、`hub_diameter`、`bore_diameter`、`blade_count`、`blade_height`、`blade_thickness`、`blade_sweep_angle`、`blade_start_radius`、`blade_end_radius`、`backplate_thickness`。
|
||||
- feature roles：`backplate`、`hub`、`bore`、`main_blades`、可选 `splitter_blades`、`blade_root_fillets`。
|
||||
- 建模顺序：背板/轮毂；生成一片扫掠或 loft 叶片；环向阵列；切中心孔；叶根圆角。
|
||||
- 常见失败：像平面风扇；叶片不连到轮毂；叶片数错；没有中心孔。
|
||||
|
||||
### 涡轮叶片
|
||||
|
||||
不适合作为 references-only 优化对象。
|
||||
|
||||
原因：真实涡轮叶片需要翼型截面、扭转、平台、榫根、冷却孔、材料/工艺约束和严格曲面质量。reference 只能生成玩具级外形，不能可靠优化工业涡轮叶片。因此不写实施计划。
|
||||
|
||||
### 螺旋桨
|
||||
|
||||
不适合作为通用 references-only 优化对象。
|
||||
|
||||
原因：螺旋桨需要直径、桨距或桨距分布、翼型截面、扭转、弦长分布、桨毂、应用场景。缺少这些时，reference 只会得到“视觉像螺旋桨”的模型，而不是正确叶片。因此不写实施计划。
|
||||
|
||||
### 凸轮
|
||||
|
||||
当作为“带厚度的 2D 轮廓凸轮”时适合；不适合没有运动规律的动态设计验证。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`凸轮`、`cam`、`disk cam`、`cam profile`、`lift curve`。
|
||||
- 不变量：非圆轮廓；绕中心旋转；驱动从动件升程；中心孔或安装孔；厚度。

|
||||

|
||||
- 建模顺序：根据简化运动规律生成闭合 2D 极坐标轮廓；拉伸；切中心孔/键槽；倒角。
|
||||
- 常见失败：只是圆盘加凸点；轮廓不光顺；无中心孔；轮廓自交。
|
||||
|
||||
## 6. 模具零件
|
||||
|
||||
代表件：注塑模仁、压铸模芯、冲压模具镶件。
|
||||
|
||||
共同判断：模仁/模芯主形状通常来自产品几何的正负形，不适合靠通用 reference 猜出来。references-only 只适合辅助特征，如螺钉孔、销孔、冷却孔、基准面、避空和安装方式。
|
||||
|
||||
### 注塑模仁/型腔镶件
|
||||
|
||||
不适合作为 references-only 优化对象。
|
||||
|
||||
原因：核心型腔面取决于塑件几何、缩水率、拔模、顶出、浇口、冷却、分型线和模架结构。没有产品几何时，reference 无法决定主形体。因此不写实施计划。
|
||||
|
||||
### 压铸模芯
|
||||
|
||||
不适合作为 references-only 优化对象。
|
||||
|
||||
原因：压铸模芯依赖铸件产品、分型策略、滑块/抽芯、拔模、浇排系统、热管理和合金工艺。reference-only 无法可靠优化。因此不写实施计划。
|
||||
|
||||
### 冲压模具镶件
|
||||
|
||||
对简单镶件、冲头、凹模套、轮廓块适合；复杂成形镶件仍需工艺设计。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`冲压模具镶件`、`stamping die insert`、`punch insert`、`die button`。
|
||||

|
||||
- feature roles：`insert_body`、`working_edge_or_profile`、`screw_holes`、`dowel_holes`、`relief_pocket`、`datum_faces`。
|
||||
- 建模顺序：块体；切/凸出工作轮廓；加避空；切定位孔和螺钉孔；倒非工作边。
|
||||
- 常见失败：没有定位孔；工作刃口和避空不区分；只做装饰轮廓；声称冲裁间隙正确。
|
||||
|
||||
## 7. 精密零件
|
||||
|
||||
代表件：量规、夹具定位件、光学基座、医疗器械零件。
|
||||
|
||||
共同边界：references 可以改善结构和基准表达，但不能声明公差、校准、计量认证、医疗合规或光学性能。
|
||||
|
||||
### 量规
|
||||
|
||||
适合简单量规几何；不适合认证计量。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`量规`、`gauge`、`go/no-go gauge`、`inspection gauge`。
|
||||
- 不变量：受控测量几何；手柄或主体；测量开口/塞规/环规特征；基准面或标识。

|
||||
- 建模顺序：平面量规主体；切测量开口；加手柄/避空；倒安全边。
|
||||
- 常见失败：像装饰尺子；没有实际测量特征；声称已校准。
|
||||
|
||||
### 夹具定位件
|
||||
|
||||
高度适合 references-only 优化。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`夹具定位件`、`定位块`、`fixture locator`、`locating block`、`datum block`。
|
||||
- 不变量：定位基准面；定位销/销孔；安装孔；夹持或接触面；重复定位逻辑。
|
||||
- 变体：定位块、V 形块、止挡块、销定位件、支承垫块。
|
||||
- 默认：矩形定位块，基准面、两个销孔、安装孔；如果定位圆料则加 V 槽或台阶。
|
||||
- 参数角色：`block_length`、`block_width`、`block_height`、`datum_face_offset`、`dowel_pin_diameter`、`dowel_spacing`、`mounting_hole_diameter`、`v_groove_angle`、`step_height`。
|
||||
- feature roles：`locator_body`、`datum_faces`、`dowel_holes`、`mounting_holes`、`contact_surface`、`v_groove_or_step`。
|
||||
- 建模顺序：块体；加工基准/接触特征；切销孔和安装孔；倒角。
|
||||
- 常见失败：没有基准；孔位不相对基准定义；只是普通块；定位孔布局过约束。
|
||||
|
||||
### 光学基座
|
||||
|
||||
适合结构 reference；不适合声明光学平面度或对准精度。
|
||||
|
||||
实施计划：
|
||||
|
||||
- 识别：`光学基座`、`optical base`、`optical mounting base`、`precision base`。
|

|
||||
- 建模顺序：基座；切孔阵列；加凸台/槽；倒角。
|
||||
- 常见失败：随机装饰孔；没有基准边；声称光学平面度。
|
||||
|
||||
### 医疗器械零件
|
||||
|
||||
不适合作为一个通用 references-only 代表件。
|
||||
|
||||
原因：`医疗器械零件` 范围过宽，而且常涉及安全、法规、材料、生物相容性、灭菌和临床用途。可以针对明确几何子类写 reference，例如简单手术夹具、定位块、试模件，但不能对这个大类做通用优化。因此不写实施计划。
|
||||
|
||||
## 优先级建议
|
||||
|
||||
最适合第一批做 reference 的代表件：
|
||||
|
||||
- 阶梯轴
|
||||
- 传动轴
|
||||
- 法兰盘
|
||||
- 端盖
|
||||
- 轴承座
|
||||
- 安装底板
|
||||
- 连接板
|
||||
- 夹具定位件
|
||||
- 简化叶轮
|
||||
- 凸轮
|
||||
|
||||
暂不建议作为 reference-only 首批目标：
|
||||
|
||||
- 发动机缸体/缸盖
|
||||
- 涡轮叶片
|
||||
- 螺旋桨
|
||||
- 注塑模仁/型腔镶件
|
||||
- 压铸模芯
|
||||
- 泛化的医疗器械零件
|
||||
|
||||
这些对象需要标准、产品几何、截面曲线、运动规律、工艺决策、性能计算或法规边界。只靠 reference 很容易生成“像”，但不容易生成“对”。
|
||||
|
||||
## 在 text-to-cad 中的使用建议
|
||||
|
||||
只做 references 时，推荐先把本文拆成 7 个短 reference 文件，并在 `skills/cad/SKILL.md` 的 `Progressive references` 中加触发说明：
|
||||
|
||||
- 用户请求出现轴、主轴、丝杠、花键、键槽时，加载 `part-families/shaft.md`。
|
||||
- 出现法兰、端盖、轴承座、同步带轮、齿轮毛坯时，加载 `part-families/disc-sleeve.md`。
|
||||
- 出现箱体、壳体、减速器壳、泵体时，加载 `part-families/housing.md`。
|
||||
- 出现底板、连接板、模板、面板时，加载 `part-families/plate.md`。
|
||||
- 出现叶轮、凸轮、叶片、螺旋桨时，加载 `part-families/freeform-surface.md`，并对不适合项保持强 caveat。
|
||||
- 出现模仁、模芯、冲压镶件时，加载 `part-families/mold-tooling.md`，并提醒主形体需要产品几何。
|
||||
- 出现量规、夹具定位、光学基座、医疗件时，加载 `part-families/precision-fixture.md`，并避免精度/合规承诺。
|
||||
|
||||
这一步会影响生成，因为 CAD agent 在写代码前会获得“这类零件应该有哪些结构”的上下文。但它不会像 factory 那样强制固定几何，也不会像 validator 那样保证正确性。

# CNC machined part family reference optimization plan
|
||||
|
||||
This document is a first-pass implementation plan for improving `text-to-cad`
|
||||
generation quality using reference guidance only. It is not a validator or a
|
||||
factory design. The goal is to teach the CAD agent the recurring geometry,
|
||||
datum choices, parameter roles, feature roles, and common failure modes of
|
||||
common CNC machined part families before it writes build123d source.
|
||||
|
||||
Research sources used for this plan include public CNC design-for-machining
|
||||
guides from Protolabs and Xometry, flange references from Texas Flange and
|
||||
ASME-flange guides, bearing-housing descriptions from ASKUBAL, lead-screw and
|
||||
spline references from Roton, igus, Machinery's Handbook excerpts, and online
|
||||
manufacturing articles on gearbox housings, impellers, propellers, mold
|
||||
components, and fixture parts. These sources should be treated as guidance for
|
||||
recognition and modeling structure, not as a substitute for standards, drawings,
|
||||
tolerances, or certification.
|
||||
|
||||
## Reference optimization principle
|
||||
|
||||
References should improve the first generated model without locking all output
|
||||
to one template. Each part-family reference should be written as:
|
||||
|
||||
1. Recognition terms: English and Chinese names, aliases, and adjacent part names.
|
||||
2. Invariants: features that must exist for the part to be semantically correct.
|
||||
3. Variants: common forms the user may ask for.
|
||||
4. Default strategy: what to do when the user gives no variant.
|
||||
5. Parameter roles: dimensions that must become named parameters.
|
||||
6. Feature roles: modeling units the agent should plan explicitly.
|
||||
7. Construction sequence: safe build123d order.
|
||||
8. Common failures: mistakes the reference should actively prevent.
|
||||
9. Validation targets: geometry facts to inspect manually or with generic CAD tools.
|
||||
|
||||
Important: references are soft constraints. They should say "default to" and
|
||||
"unless the user specifies otherwise", not "always generate this exact shape".
|
||||
|
||||
## Cross-family CNC modeling rules
|
||||
|
||||
Use these rules in every part-family reference:
|
||||
|
||||
- Keep all functional dimensions as named parameters, not buried numbers.
|
||||
- Choose the origin from the dominant functional datum: shaft axis, bearing axis,
|
||||
plate center, mounting face, split face, or sealing face.
|
||||
- Build base geometry first, cut primary holes/bores second, add secondary
|
||||
holes/pockets/slots third, and apply fillets/chamfers last.
|
||||
- Prefer standard drilled/tapped/clearance hole sizes when the user does not
|
||||
give a custom size.
|
||||
- Avoid thin walls, deep narrow pockets, blind holes without depth, tiny features,
|
||||
and square internal corners unless explicitly requested.
|
||||
- For CNC-like models, use internal radii or relieved corners for milled pockets;
|
||||
use external chamfers for handling and deburring.
|
||||
- For multi-face parts, preserve datum relationships over visual symmetry.
|
||||
- Do not claim real machinability, tolerance compliance, sealing performance,
|
||||
fatigue strength, medical suitability, or aerospace suitability from reference
|
||||
guidance alone.
|
||||
|
||||
## Suggested reference file layout
|
||||
|
||||
Do not create dozens of files immediately. Start with seven family references:
|
||||
|
||||
- `references/part-families/shaft.md`
|
||||
- `references/part-families/disc-sleeve.md`
|
||||
- `references/part-families/housing.md`
|
||||
- `references/part-families/plate.md`
|
||||
- `references/part-families/freeform-surface.md`
|
||||
- `references/part-families/mold-tooling.md`
|
||||
- `references/part-families/precision-fixture.md`
|
||||
|
||||
Later, split high-value representatives such as flange, bearing housing, stepped
|
||||
shaft, mounting plate, and timing pulley into dedicated files only if the broad
|
||||
family references are not enough.
|
||||
|
||||

|
||||
|
||||
### Engine block / cylinder head
|
||||
|
||||
Suitability: not suitable for references-only optimization as a representative
|
||||
industrial part. The real geometry depends on combustion chamber design,
|
||||
cylinder layout, valve train, water jackets, oil galleries, head gasket pattern,
|
||||
casting constraints, and application-specific standards. A reference can help
|
||||
make an educational simplified block/head, but it should not be used as a
|
||||
general optimized CNC part family. No implementation plan.
|
||||
|
||||
### Pump body
|
||||
|
||||
Suitability: suitable only for simplified pump-body references; not suitable for
|
||||
accurate hydraulic/flow performance without drawings or CFD geometry.
|
||||
|
||||

|
||||
casing, bearing-frame pump body.

|
||||
seal_bore, cover_bolt_pattern, mounting_feet.
|
||||

|
||||
bosses/flanges; cut passages as simplified cylinders/sweeps; add cover bolt
|
||||
pattern and feet; fillet last.
|
||||
- Common failures to prevent: ordinary box with holes, missing volute/chamber,
|
||||
inlet/outlet not connected, no mounting/sealing face.
|
||||
- Validation targets: chamber existence, inlet/outlet axes, flange bolt patterns,
|
||||
seal bore coaxiality, wall continuity.
|
||||
|
||||

|
||||
- Feature roles: template_outline, guide_holes, alignment_notches, slots,
|
||||
reference_edges.
|
||||
- Construction sequence: outline; cut guide features; add notches; chamfer.
|
||||

|
||||
- Validation targets: panel size, cutout size/position, hole count, thickness.
|
||||
|
||||
## 5. Freeform and curved-surface parts
|
||||
|
||||
Representative parts: impeller, turbine blade, propeller, cam.
|
||||
|
||||
Family recognition terms:
|
||||
|
||||
- English: impeller, turbine blade, propeller, cam, airfoil, blade, helical,
|
||||
swept, twisted.
|
||||
- Chinese: 叶轮, 涡轮叶片, 螺旋桨, 凸轮, 叶片, 扭转, 曲面.
|
||||
|
||||
### Impeller
|
||||
|
||||
Suitability: suitable for simplified references optimization. Exact hydraulic or
|
||||
aero performance requires blade curves or a drawing.
|
||||
|
||||
Implementation plan:
|
||||
|
||||
- Recognition: `impeller`, `centrifugal impeller`, `compressor wheel`, `叶轮`.
|
||||
- Invariants: central hub, bore, backplate or shroud depending on variant,
|
||||
repeated blades, rotational symmetry.
|
||||
- Variants: open impeller, semi-open impeller, closed impeller, splitter blades,
|
||||
backward-curved blades.

||||
bore coaxiality, blade attachment.
|
||||
|
||||
### Turbine blade
|
||||
|
||||
Suitability: not suitable for references-only optimization as a general
|
||||
representative part. Real turbine blades require airfoil sections, twist,
|
||||
platform/root geometry, material/process constraints, cooling holes, and strict
|
||||
surface quality. A reference can produce a toy blade, but it will not improve
|
||||
industrial turbine-blade generation reliably. No implementation plan.
|
||||
|
||||
### Propeller
|
||||
|
||||
Suitability: not suitable for references-only optimization as a general
|
||||
representative part. A propeller needs diameter, pitch or pitch distribution,
|
||||
airfoil sections, blade twist, chord distribution, hub geometry, and application
|
||||
context. Without those, references only produce a plausible visual propeller.
|
||||
No implementation plan.
|
||||
|
||||
### Cam
|
||||
|
||||
Suitability: suitable when the cam is treated as a 2D profile with thickness;
|
||||
not suitable for dynamic design validation without motion law data.
|
||||
|
||||
Implementation plan:
|
||||
|
||||
- Recognition: `cam`, `disk cam`, `凸轮`, `cam profile`, `lift curve`.
|
||||
- Invariants: rotating body with non-circular profile that drives follower lift;
|
||||
bore/keyway or mounting hole; thickness.
|
||||
- Variants: eccentric cam, plate cam, radial disk cam, groove cam simplified as
|
||||
face groove.
|
||||
- Default: plate cam with base circle, one rise-dwell-return lobe, central bore,
|
||||
and keyway if torque transfer is requested.

|
||||
return_angle, follower_radius, thickness, bore_diameter, keyway_width.
|
||||
- Feature roles: cam_profile, base_circle, lobe, bore, keyway, optional_groove.
|
||||
- Construction sequence: generate 2D polar profile from simple motion law or
|
||||
simplified lobe curve; extrude; cut bore/keyway; chamfer edges.
|
||||

|
||||
lobe not smooth, no bore, profile self-intersection.
|
||||

|
||||
smooth closed outline.
|
||||
|
||||
## 6. Mold parts
|
||||
|
||||
Representative parts: injection mold core/cavity insert, die-casting core, stamping die insert.
|
||||

|
||||
|
||||
### Injection mold core/cavity insert
|
||||
|
||||
Suitability: not suitable for references-only optimization as a representative
|
||||
part unless the molded-product geometry is supplied. The core/cavity surface is
|
||||
the negative/positive of a product and depends on shrinkage, draft, ejection,
|
||||
cooling, gates, and parting-line decisions. References can guide auxiliary
|
||||
features, but not the main form. No implementation plan.
|
||||
|
||||
### Die-casting core
|
||||
|
||||
Suitability: not suitable for references-only optimization as a representative
|
||||
part without the cast product, parting strategy, slides/cores, draft, gating,
|
||||
thermal management, and alloy process constraints. No implementation plan.
|
||||
|
||||
### Stamping die insert
|
||||
|
||||
Suitability: limited but suitable for simple inserts, punches, die buttons, and
|
||||
profile blocks when the cutting/forming profile is specified.

|
||||
|
||||

|
||||
`冲压模具镶件`.
|
||||
- Invariants: tool-steel block or round insert, working profile/cut edge,
|
||||
locating features, fastener holes, relief/clearance.
|
||||
- Variants: rectangular profile insert, round die button, punch insert,
|
||||
stripper-related insert.
|
||||
- Default: rectangular insert block with specified working profile pocket or
|
||||

|
||||
- Parameter roles: block_length, block_width, block_height, working_profile,
|
||||
clearance_offset, screw_hole_positions, dowel_hole_positions, relief_depth.
|
||||
- Feature roles: insert_body, working_edge_or_profile, screw_holes, dowel_holes,
|
||||
relief_pocket, datum_faces.
|
||||
- Construction sequence: block; cut/raise working profile; add relief; cut
|
||||
locating and screw holes; chamfer non-working edges.
|
||||
- Common failures to prevent: ignoring locating holes, decorative profile with
|
||||
no datum, working edge not separated from relief, claiming cutting clearance.
|
||||
- Validation targets: body size, profile presence, screw/dowel hole positions,
|
||||
relief side, datum faces.
|
||||
|
||||
## 7. Precision parts
|
||||
|
||||

|
||||
|
||||
Shared boundary:
|
||||
|
||||
- References can improve geometric structure and datum clarity.
|
||||
- References must not claim tolerance, calibration, metrology certification,
|
||||
medical compliance, or optical performance.
|
||||
|
||||
### Gauge
|
||||
|
||||
Suitability: suitable for simple gauge geometry; not for certified metrology.
|
||||
|
||||
Implementation plan:
|
||||
|
||||
- Recognition: `gauge`, `go/no-go gauge`, `inspection gauge`, `量规`.
|
||||
- Invariants: controlled reference geometry, handle/body, measuring feature,
|
||||
datum or label.
|
||||
- Variants: plug gauge, ring gauge, gap gauge, profile gauge, step gauge.
|
||||
- Default: if unspecified, create a simple step/gap gauge with labeled measuring
|
||||

|
||||
- Parameter roles: nominal_size, go_size, no_go_size, gauge_thickness,
|
||||
handle_length, measuring_slot_width, relief_radius.
|
||||
- Feature roles: gauge_body, measuring_feature, handle, datum_face,
|
||||
relief_notches.
|
||||
- Construction sequence: flat gauge body; cut measuring openings; add handle and
|
||||
reliefs; chamfer safe edges.

||||
- Validation targets: measuring slot/ring/plug size, thickness, handle, datum.
|
||||
|
||||
### Fixture locating part

|
||||
|
||||
Implementation plan:
|
||||
|
||||
- Recognition: `fixture locator`, `locating block`, `datum block`,
|
||||
`夹具定位件`, `定位块`.
|
||||
- Invariants: datum faces, locating pins/holes, mounting holes, clamping/contact
|
||||
surfaces, repeatable positioning logic.
|
||||

||||
- Validation targets: datum face existence, dowel-hole count/spacing, mounting
|
||||
holes, contact surface geometry.
|
||||
|
||||
### Optical base
|
||||
|
||||
Suitability: suitable for structural reference guidance, not optical alignment
|
||||
claims.
|
||||
|
||||
Implementation plan:
|
||||
|
||||
- Recognition: `optical base`, `optical mounting base`, `光学基座`.
|
||||
- Invariants: flat base, grid or pattern of threaded/clearance holes, raised
|
||||
pads or rails, datum edges, stable support.
|
||||
- Variants: optical breadboard-like base, lens mount base, rail adapter, prism
|
||||
mount base.

|
||||
|
||||
### Medical device part
|
||||
|
||||
Suitability: not suitable as a single references-only representative. "Medical
|
||||
device part" is too broad and often safety/regulatory-critical. References can
|
||||
be written for a specific geometry such as a simple surgical fixture, clamp, or
|
||||
implant trial, but not for the category as a whole. No implementation plan.
|
||||
|
||||
## Rollout plan for reference-only optimization
|
||||
|
||||
1. Add a short trigger section to `skills/cad/SKILL.md` that tells the agent to
|
||||
load a part-family reference after the CAD brief and before planning geometry.
|
||||
2. Create the seven broad family reference files listed above.
|
||||
3. Keep each family reference under roughly 150-220 lines so the agent can load
|
||||
it without drowning out the user request.
|
||||
4. Start with the highest-return families:
|
||||
- `plate.md`
|
||||
- `disc-sleeve.md`
|
||||
- `shaft.md`
|
||||
- `housing.md`
|
||||
5. Add `freeform-surface.md`, `mold-tooling.md`, and `precision-fixture.md`
|
||||
with stronger caveats because these families contain unsuitable subtypes.
|
||||
6. Run A/B manual checks on representative prompts before adding validators or
|
||||
factories.
|
||||
|
||||
## Recommended first references
|
||||
|
||||
The first version should prioritize the representatives with the best
|
||||
reference-only payoff:
|
||||
|
||||
- Stepped shaft
|
||||
- Drive shaft
|
||||
- Flange
|
||||
- End cover
|
||||
- Bearing housing
|
||||
- Mounting base plate
|
||||
- Connecting plate
|
||||
- Fixture locating part
|
||||
- Simple impeller
|
||||
- Cam
|
||||
|
||||
Do not start reference-only rollout with:
|
||||
|
||||
- Engine block/cylinder head
|
||||
- Turbine blade
|
||||
- Propeller
|
||||
- Injection mold core/cavity insert
|
||||
- Die-casting core
|
||||
- Generic medical device part
|
||||
|
||||
These require product geometry, curves, standards, regulatory constraints, or
|
||||
domain calculations that references alone cannot supply reliably.

# Plate Like Reference
|
||||
|
||||
## When to read this file
|
||||
|
||||
Read this reference when the request matches these triggers:
|
||||
|
||||
- `bracket`
|
||||
- `plate`
|
||||
- `支架`
|
||||
- `板`
|
||||
|
||||
## Object boundary
|
||||
|
||||
Use this reference to improve first-pass CAD modeling structure. It is not a validator, factory, or engineering certification. Do not model adjacent assemblies unless the user explicitly requests them.
|
||||
|
||||
## Recognition
|
||||
|
||||
This node represents `mechanical_part.plate_like` in the generated taxonomy. It was mined from 2 source models.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- The main body is a flat prismatic plate.
|
||||
- Holes, slots, and pockets should be positioned from datum edges or centerlines.
|
||||
- Thickness and edge treatment should be named.
|
||||
|
||||
## Common variants
|
||||
|
||||
- Keep variants driven by the user prompt and source evidence.
|
||||
- Prefer adding a child variant skill when one branch becomes too specific.
|
||||
- Do not collapse all examples into one fixed template.
|
||||
|
||||
## Required parameter roles
|
||||
|
||||
- `datum_edges`
|
||||
- `flat_body`
|
||||
- `holes_or_slots`
|
||||
|
||||
## Feature roles
|
||||
|
||||
- `datum_edges`
|
||||
- `flat_body`
|
||||
- `holes_or_slots`
|
||||
|
||||
## Operation / construction sequence
|
||||
|
||||
1. Build the primary base solid first.
|
||||
2. Add major bosses or protrusions second.
|
||||
3. Apply subtractive cuts, holes, pockets, and slots after the base is valid.
|
||||
4. Create repeated features through patterns rather than independent ad hoc geometry.
|
||||
5. Apply fillets and chamfers last.
|
||||
|
||||
## Common failures to prevent
|
||||
|
||||
- Unnamed magic dimensions hidden inside geometry calls.
|
||||
- Decorative features with no functional role.
|
||||
- Fillets or chamfers applied before major cuts.
|
||||
- Claiming engineering performance or standard compliance from reference guidance alone.
|
||||
|
||||
## Validation targets
|
||||
|
||||
- The generated model contains the core invariants above.
|
||||
- Major feature roles are visible or represented by named parameters.
|
||||
- Repeated features have consistent count, spacing, and datum relationship.
|
||||
- The output is a valid solid or explicitly requested assembly.
|
||||
|
||||
## Exclusions

# Bearing housing reference
|
||||
|
||||
Read this file when the request is for a bearing housing, bearing seat, bearing
|
||||
support, pillow block, flanged bearing housing, cartridge bearing holder,
|
||||
`轴承座`, `轴承支座`, `轴承座壳体`, or `带座轴承` housing.
|
||||
|
||||
This reference improves first-pass geometry structure only. It does not certify
|
||||
bearing fit, tolerance class, coaxiality, lubrication, load capacity, sealing,
|
||||
casting quality, or manufacturability.
|
||||
|
||||
## Object boundary
|
||||
|
||||
By default, model the machined housing/seat part that supports a bearing. Do not
|
||||
model the rolling elements, cage, shaft, bolts, grease nipple, seals, or a full
|
||||
mounted-bearing assembly unless the user explicitly asks for those as separate
|
||||
parts.
|
||||
|
||||
If the prompt says `bearing`, `bearing seat`, or `轴承座` without more detail,
|
||||
the semantic core is the support body with a bearing bore and mounting features.
|
||||
|
||||
## Recognition
|
||||
|
||||
Use this reference when the request includes:
|
||||
|
||||
- English: bearing housing, bearing seat, bearing support, pillow block,
|
||||
plummer block, flanged bearing housing, cartridge bearing holder.
|
||||
- Chinese: 轴承座, 轴承支座, 轴承座壳体, 立式轴承座, 法兰轴承座, 带座轴承.
|
||||
- Adjacent intent: shaft clearance, bearing bore, bearing pocket, mounting feet,
|
||||
flange mount, bolt holes, cap, split housing, support ribs, grease port.
|
||||
|
||||
## Core invariants
|
||||
|
||||
A generated bearing housing should include:
|
||||
|
||||
- A bearing bore or bearing pocket sized by a named bearing outer diameter.
|
||||
- A shaft clearance axis coaxial with the bearing bore.
|
||||
- Material around the bore thick enough to read as support, not just a thin ring.
|
||||
- A mounting method: base feet, flange, side lugs, or plate mount.
|
||||
- Mounting holes with symmetric placement relative to the functional datum.
|
||||
- A stable datum convention: bearing axis and mounting face are primary.
|
||||
- Edge relief: practical chamfers/fillets after major cuts.
|
||||
|
||||
For a pillow-block style housing, the minimum recognizable structure is:
|
||||
|
||||
- Flat base.
|
||||
- Raised bearing boss or arched support.
|
||||
- Horizontal bearing bore through the support.
|
||||
- Two base mounting holes.
|
||||
- Optional ribs connecting boss to base.
|
||||
|
||||
## Default strategy
|
||||
|
||||
When under-specified, generate a simple pillow-block bearing housing:
|
||||
|
||||
- Bearing axis along X.
|
||||
- Flat rectangular base on the XY plane.
|
||||
- Bearing center above the base by `bearing_center_height`.
|
||||
- Cylindrical or rounded boss around the bearing bore.
|
||||
- Coaxial through bore for shaft clearance plus a larger bearing seat/pocket.
|
||||
- Two elongated or round mounting holes in the base, symmetric about the Y axis.
|
||||
- Two ribs from base to bearing boss if there is enough room.
|
||||
- Fillets/chamfers last.
|
||||
|
||||
Do not default to a full assembly. Do not default to visible bearing balls. Do
|
||||
not default to a random bracket with holes but no bearing bore.
|
||||
|
||||
## Common variants
|
||||
|
||||
### Pillow block / plummer block
|
||||
|
||||
- Base-mounted housing with horizontal bearing axis.
|
||||
- Two or four mounting holes in the base.
|
||||
- Raised central boss, arch, or saddle around the bore.
|
||||
- Optional split cap only if the user asks for split housing or cap bolts.
|
||||
|
||||
### Flanged bearing housing
|
||||
|
||||
- Circular, square, oval, or diamond flange around the bearing bore.
|
||||
- Bearing axis usually normal to the flange face.
|
||||
- Bolt holes arranged on a bolt circle or symmetric flange pattern.
|
||||
- Optional pilot lip or locating register on the mounting face.
|
||||
|
||||
### Plate-mounted bearing seat
|
||||
|
||||
- Flat or block-like plate with bearing pocket.
|
||||
- Bearing axis may be normal to the plate.
|
||||
- Mounting holes belong to the plate datum, not random locations.
|
||||
|
||||
### Split bearing housing
|
||||
|
||||
- Lower base and upper cap are separate parts or clearly separated bodies.
|
||||
- Cap bolts and split plane must be represented if split form is requested.
|
||||
- If source-level assembly is not needed, a simplified monolithic split-line
|
||||
groove is acceptable, but label the assumption.
|
||||
|
||||
### Cartridge bearing holder
|
||||
|
||||
- Cylindrical sleeve-like body with flange or clamp features.
|
||||
- Bearing pocket and shaft clearance are coaxial.
|
||||
- Include retaining shoulder or snap-ring groove when requested.
|
||||
|
||||
## Required parameter roles
|
||||
|
||||
Use semantic parameters before modeling:
|
||||
|
||||
- `bearing_outer_diameter`
|
||||
- `bearing_width`
|
||||
- `shaft_diameter`
|
||||
- `shaft_clearance_diameter`
|
||||
- `bearing_bore_diameter`
|
||||
- `bearing_bore_depth`
|
||||
- `bearing_center_height`
|
||||
- `wall_thickness`
|
||||
- `base_length`
|
||||
- `base_width`
|
||||
- `base_thickness`
|
||||
- `mount_hole_diameter`
|
||||
- `mount_hole_spacing_x`
|
||||
- `mount_hole_spacing_y`
|
||||
- `boss_outer_diameter`
|
||||
- `boss_width`
|
||||
- `flange_outer_diameter`
|
||||
- `flange_thickness`
|
||||
- `bolt_count`
|
||||
- `bolt_circle_diameter`
|
||||
- `rib_thickness`
|
||||
- `fillet_radius`
|
||||
|
||||
Only define optional parameters used by the selected variant.
|
||||
|
||||
## Feature roles to plan explicitly
|
||||
|
||||
Use these roles in the CAD brief and source structure:
|
||||
|
||||
- `mounting_base`
|
||||
- `bearing_boss`
|
||||
- `bearing_seat_bore`
|
||||
- `shaft_clearance_bore`
|
||||
- `mounting_holes`
|
||||
- `flange_mount`
|
||||
- `pilot_lip`
|
||||
- `support_ribs`
|
||||
- `split_cap`
|
||||
- `cap_bolts`
|
||||
- `retaining_groove`
|
||||
- `grease_port`
|
||||
- `datum_mounting_face`
|
||||
- `datum_bearing_axis`
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Select the variant from the prompt. If no variant is specified, use pillow
|
||||
block.
|
||||
2. Define the datum system:
|
||||
- pillow block: base bottom face is Z=0; bearing axis is X.
|
||||
- flanged housing: flange mounting face is the primary plane; bore axis is
|
||||
normal to it.
|
||||
3. Build the base, flange, or plate body first.
|
||||
4. Add the bearing boss/support body and ensure it intersects the base/flange.
|
||||
5. Cut the shaft clearance bore and bearing seat coaxially.
|
||||
6. Cut mounting holes using symmetric positions or bolt circle pattern.
|
||||
7. Add ribs only when they intersect both base/flange and boss.
|
||||
8. Add optional split line, cap features, grease port, retaining groove, or pilot
|
||||
lip if requested.
|
||||
9. Apply chamfers and fillets last.
|
||||
|
||||
For through bores and mounting holes, overshoot cutting tools through the target
|
||||
faces. Avoid coplanar cutting tools.
|
||||
|
||||
## Common failures to prevent
|
||||
|
||||
- A generic bracket with no bearing bore.
|
||||
- A ring with no mounting method.
|
||||
- Bearing bore and shaft clearance not coaxial.
|
||||
- Missing bearing center height in pillow-block form.
|
||||
- Mounting holes asymmetric when the variant implies symmetry.
|
||||
- Ribs that float or only touch at an edge.
|
||||
- Base thinner than mounting-hole diameter without reason.
|
||||
- Side openings or decorative slots with no bearing-seat purpose.
|
||||
- Generating balls, cages, shafts, fasteners, or seals when the user asked only
|
||||
for the housing.
|
||||
- Confusing bearing housing with shaft, flange, or motor mount.
|
||||
|
||||
## Validation targets
|
||||
|
||||
After generation, inspect or reason about:
|
||||
|
||||
- Bearing bore diameter/depth and shaft clearance diameter.
|
||||
- Coaxiality of bearing bore and shaft clearance.
|
||||
- Bearing center height above mounting face for pillow-block form.
|
||||
- Base or flange dimensions and thickness.
|
||||
- Mounting-hole count, size, and symmetry or bolt-circle diameter.
|
||||
- Boss wall thickness around bearing seat.
|
||||
- Rib attachment to both base/flange and boss when ribs exist.
|
||||
- Single connected solid unless the user requested an assembly or split housing.

# Cup / mug reference
|
||||
|
||||
Read this file when the request is for a drinking vessel: cup, mug, water cup,
|
||||
tumbler, drinking cup, tea cup, coffee cup, handled cup, travel mug,
|
||||
`水杯`, `杯子`, `马克杯`, or `茶杯`.
|
||||
|
||||
This reference improves first-pass geometry structure only. It does not certify
|
||||
food safety, insulation, thermal performance, ergonomics, leak resistance, or
|
||||
manufacturability.
|
||||
|
||||
## Recognition
|
||||
|
||||
Use this reference when the prompt describes a vessel whose primary geometry is
|
||||
an open container for liquid. Distinguish the common cases:
|
||||
|
||||
- `cup` / `水杯` / `drinking cup`: default open cup, usually without handle.
|
||||
- `mug` / `马克杯` / `handled cup`: open cup with one handle on the side.
|
||||
- `tumbler`: taller cup, optionally with a lid, usually without handle.
|
||||
- `travel mug`: handled cup with a lid; may be an assembly if the lid is modeled.
|
||||
- `bottle`: do not use this reference unless the user explicitly wants a cup-like
|
||||
bottle or bottle mug hybrid.
|
||||
|
||||
If the prompt does not mention a handle, do not add one by default.
|
||||
|
||||
## Core invariants
|
||||
|
||||
A recognizable cup should have:
|
||||
|
||||
- An open top.
|
||||
- A hollow interior cavity.
|
||||
- A continuous side wall.
|
||||
- A closed bottom.
|
||||
- A continuous rim at the opening.
|
||||
- A stable standing base or foot ring.
|
||||
|
||||
A handled mug should add:
|
||||
|
||||
- Exactly one main handle unless the prompt requests multiple handles.
|
||||
- The handle mounted on one side of the cup body.
|
||||
- Two attachment regions that intersect the cup body solidly.
|
||||
- A clear gap between handle and cup body so the hand can pass through.
|
||||
- A loop, C-shape, or arched form that reads as a graspable handle, not a fin,
|
||||
tab, rib, or broken bracket.
|
||||
|
||||
## Default strategy
|
||||
|
||||
When the request is just `cup` or `水杯`, generate a simple open cup with no
|
||||
handle:
|
||||
|
||||
- Revolved outer body.
|
||||
- Hollow interior.
|
||||
- Closed bottom.
|
||||
- Slight outward taper or cylindrical wall.
|
||||
- Small rim radius or lip.
|
||||
- Optional foot ring.
|
||||
|
||||
When the request is `mug`, `马克杯`, or `handled cup`, generate the same cup
|
||||
body plus one handle.
|
||||
|
||||
## Handle strategy
|
||||
|
||||
The handle is the failure-prone part, so make it explicit:
|
||||
|
||||
- The handle must be a single continuous shape.
|
||||
- It should attach to the cup body at two distinct points on the same side.
|
||||
- The two attachment points should be vertically separated and usually near the
|
||||
upper-middle and lower-middle height of the cup.
|
||||
- The handle should project outward far enough to create finger clearance, but
|
||||
not so far that it looks like a secondary looped part.
|
||||
- The handle cross-section should be rounded or softly rectangular, not a thin
|
||||
blade.
|
||||
- The handle opening should remain open; do not fill the inside of the loop with
|
||||
a solid web unless the prompt asks for a closed grip.
|
||||
- Avoid multiple disconnected handle fragments, fins, or stray tabs.
|
||||
- The handle should not attach at the rim edge only; it should engage the side
|
||||
wall with real thickness.
|
||||
|
||||
## Required parameter roles
|
||||
|
||||
Use semantic parameters before modeling:
|
||||
|
||||
- `height`
|
||||
- `top_outer_diameter`
|
||||
- `bottom_outer_diameter`
|
||||
- `wall_thickness`
|
||||
- `bottom_thickness`
|
||||
- `inner_depth`
|
||||
- `rim_radius`
|
||||
- `rim_thickness`
|
||||
- `foot_ring_diameter`
|
||||
- `foot_ring_height`
|
||||
- `handle_thickness`
|
||||
- `handle_width`
|
||||
- `handle_clearance`
|
||||
- `handle_projection`
|
||||
- `handle_attach_height_top`
|
||||
- `handle_attach_height_bottom`
|
||||
- `handle_attach_offset`
|
||||
- `handle_loop_radius`
|
||||
- `handle_loop_height`
|
||||
|
||||
Only define the handle parameters when a handle is requested.
|
||||
|
||||
## Feature roles to plan explicitly
|
||||
|
||||
- `cup_body`
|
||||
- `inner_cavity`
|
||||
- `rim`
|
||||
- `base`
|
||||
- `foot_ring`
|
||||
- `handle`
|
||||
- `handle_attachment_upper`
|
||||
- `handle_attachment_lower`
|
||||
- `handle_clearance`
|
||||
- `lid_seat` or `lid_interface` if a lid is requested
|
||||
|
||||
## Construction sequence
|
||||
|
||||
1. Build the cup body first using revolve or a smooth profile sweep.
|
||||
2. Hollow the interior while preserving the bottom thickness.
|
||||
3. Add the rim and optional foot ring.
|
||||
4. If a handle is requested, place it on one side only.
|
||||
5. Model the handle as one continuous loop or arched solid with two clear
|
||||
attachment zones.
|
||||
6. Fuse the handle to the cup body so it reads as one coherent mug, not as a set
|
||||
of touching tabs.
|
||||
7. Add a lid only if the prompt explicitly requests a covered container.
|
||||
8. Apply final fillets/chamfers last.
|
||||
|
||||
For the handle, the tool or sweep profile should overshoot into the cup wall at
|
||||
both attachment regions. Avoid tangent-only contact.
|
||||
|
||||
## Common failures to prevent
|
||||
|
||||
- Solid cup with no hollow interior.
|
||||
- Cup with no bottom.
|
||||
- Cup body turned into a bottle or vase shape when the prompt says cup.
|
||||
- Handle omitted when the prompt says mug or handled cup.
|
||||
- Handle added when the prompt only says cup or water cup.
|
||||
- Handle split into two disconnected pieces.
|
||||
- Handle as a tiny fin, tab, or shard instead of a loop.
|
||||
- Handle attached only at the rim edge or at one point.
|
||||
- Handle crossing through the cup cavity or cutting into the interior wall.
|
||||
- Multiple handles unless explicitly requested.
|
||||
- Lid generated when the prompt did not ask for one.
|
||||
|
||||
## Validation targets
|
||||
|
||||
After generation, inspect or reason about:
|
||||
|
||||
- Opening is on top and remains open.
|
||||
- Interior cavity exists and is connected to the opening.
|
||||
- Bottom is closed and has nonzero thickness.
|
||||
- Rim is continuous.
|
||||
- If a handle exists, exactly one main handle is present.
|
||||
- Handle has two attachment regions on the same side.
|
||||
- Handle has sufficient clearance from the cup wall.
|
||||
- Handle does not appear as a broken fragment or a separate brace.
|
||||
- The model is a single connected solid unless a lid or travel-mug assembly is
|
||||
explicitly requested.

|

## Operation / construction sequence
|
||||
|
||||
1. Build the primary base solid first.
|
||||
2. Add major bosses or protrusions second.
|
||||
3. Apply subtractive cuts, holes, pockets, and slots after the base is valid.
|
||||
4. Create repeated features through patterns rather than independent ad hoc geometry.
|
||||
5. Apply fillets and chamfers last.
|
||||
|
||||
## Common failures to prevent
|
||||
|
||||
- Unnamed magic dimensions hidden inside geometry calls.
|
||||
- Decorative features with no functional role.
|
||||
- Fillets or chamfers applied before major cuts.
|
||||
- Claiming engineering performance or standard compliance from reference guidance alone.
|
||||
|
||||
## Validation targets
|
||||
|
||||
- The generated model contains the core invariants above.
|
||||
- Major feature roles are visible or represented by named parameters.
|
||||
- Repeated features have consistent count, spacing, and datum relationship.
|
||||
- The output is a valid solid or explicitly requested assembly.

# Shaft Like Reference
|
||||
|
||||
## When to read this file
|
||||
|
||||
Read this reference when the request matches these triggers:
|
||||
|
||||
- `journal`
|
||||
- `shaft`
|
||||
- `spindle`
|
||||
- `主轴`
|
||||
- `轴`
|
||||
- `键槽`
|
||||
|
||||
## Object boundary
|
||||
|
||||
Use this reference to improve first-pass CAD modeling structure. It is not a validator, factory, or engineering certification. Do not model adjacent assemblies unless the user explicitly requests them.
|
||||
|
||||
## Recognition
|
||||
|
||||
This node represents `mechanical_part.rotating_part.shaft_like` in the generated taxonomy. It was mined from 6 source models.
|
||||
|
||||
## Core invariants
|
||||
|
||||
- A single dominant rotation axis organizes the part.
|
||||
- Cylindrical sections should be coaxial and station-based.
|
||||
- Journals, shoulders, grooves, threads, or keyways should attach to plausible axial regions.
|
||||
|
||||
## Common variants
|
||||
|
||||
- Keep variants driven by the user prompt and source evidence.
|
||||
- Prefer adding a child variant skill when one branch becomes too specific.
|
||||
- Do not collapse all examples into one fixed template.
|
||||
|
||||
## Required parameter roles
|
||||
|
||||
- `coaxial_sections`
|
||||
- `journals`
|
||||
- `main_axis`
|
||||
- `shoulders`
|
||||
|
||||
## Feature roles
|
||||
|
||||
- `coaxial_sections`
|
||||
- `journals`
|
||||
- `main_axis`
|
||||
- `shoulders`
|
||||
|
||||
## Operation / construction sequence
|
||||
|
||||
1. Define the shaft axis and axial stations first.
|
||||
2. Build the coaxial stack by revolve or fused cylinders.
|
||||
3. Cut bores, keyways, grooves, threads, or splines after the base shaft is valid.
|
||||
4. Overshoot subtractive tools through the shaft.
|
||||
5. Apply shoulder reliefs, chamfers, and fillets last.
|
||||
|
||||
## Common failures to prevent
|
||||
|
||||
- Unnamed magic dimensions hidden inside geometry calls.
|
||||
- Decorative features with no functional role.
|
||||
- Fillets or chamfers applied before major cuts.
