# 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.
|
