Backend capabilities
build123d through CAD Skill
Use as the default STEP-first backend.
Best fit:
- Brackets, connecting rods, cranks, levers, shafts, bushings, flanges, plates, housings, covers, enclosures, fixtures, and machined features.
- Parametric Python sources with holes, pockets, slots, bosses, ribs, shells, fillets, chamfers, lofts, sweeps, and revolves.
- Source-level assemblies, named datums, joints, imported components, measurements, alignment checks, and existing STEP inspection.
- STEP output compiled from executable DesignIR 2.0.
Weak signals: a specialized mechanical family already implemented by SimpleCADAPI or a browser-only execution requirement.
SimpleCADAPI
Use for its standard mechanical factories and replayable modeling graph.
Best fit:
- Spur, helical, and herringbone gears; internal ring gears; racks; cycloidal discs; ball bearings.
- Planetary and cycloidal reducers, joint actuators, and mechanism-heavy assemblies.
- Parameter expressions, operation-graph JSON, replay, semantic tags, and topology queries.
- Reusable mechanical product families whose formulas should become deterministic library functions.
Before invocation, inspect the installed package and Skill versions together. Do not mix the current single-Solid boolean API with older *rsolidlist documentation. If the installed runtime and docs disagree, stop that route and use build123d or repair the installation.
Router refinement and repair
Use text-to-cad's own requirement expansion and visual repair when requirements are vague, reference images carry important intent, or visual complexity makes one-pass generation unreliable:
- Refine the request into a measurable brief.
- Confirm important fit- or safety-critical unknowns.
- Generate and execute backend source.
- Validate deterministic geometry facts.
- Inspect a multi-view render against the brief.
- Repair visual mismatches, capped at three automatic visual rounds.
