- Short description: Create and validate one parametric CAD part, returning STEP as the primary artifact rather than a render-only image.
What this skill does
- Builds dimension-driven part geometry and exports a real STEP model with reproducible source.
- Inspects bounding box, volume, topology and named features; preview imagery is secondary evidence.
How to use
Provide units, dimensions, functional features, tolerances, references and required exports.
Example
Create a STEP-first L bracket: 80×50×5 mm, two 6 mm base holes, one 8 mm upright slot, 3 mm fillets.
Workflow
- Extract a unit-explicit feature specification and flag missing functional dimensions.
- Create reproducible parametric source with a STEP-capable kernel; never fake CAD with an image model.
- Export STEP first, then optional mesh formats; render preview only from generated geometry.
- Re-open STEP and verify dimensions, bounding box, volume, features and manifold geometry.
User-facing output
- Media type: One STEP model plus preview
- Default quantity: 1
- Content per image: One validated parametric part
- Default layout: Source-preserving or dimension-defined format
- Model policy: STEP-first parametric CAD workflow
- Downstream use: Mechanical design handoff, not engineering certification
