cad is an agent skill that creates and validates STEP-first parametric CAD models from natural-language or image input so developers can produce inspectable mechanical geometry and exports.
About
cad is an agent skill from the text-to-cad library for creating, modifying, and validating parametric CAD models with STEP as the primary artifact. Reach for it when you need mechanical parts, assemblies, enclosures, or exportable mesh formats from plain-language specs, reference images, or existing STEP files. It pairs build123d source generation with inspection, mating, and fabrication-oriented outputs instead of treating CAD as one-off mesh dumps.
- STEP-first build123d workflow with assemblies, joints, and geometry inspection
- Natural-language and image-driven part creation with validated measurements
- Secondary STL, 3MF, and native GLB exports from CAD geometry
- Part of the text-to-cad library covering robotics URDF, SDF, and local review

How do you turn plain-language or image-based part requests into checked STEP models and secondary fabrication exports inside an agent session?
Generate and inspect STEP-first parametric CAD parts and assemblies from natural language, images, or drawings, with STL, 3MF, and GLB exports.
Who is it for?
Developers building hardware, enclosures, or robotics artifacts who want STEP-first CAD generation with agent-guided inspection in a local repo.
Skip if: Teams that only need render-only concept art, CAM toolpaths, certified FEA sign-off, or architectural BIM without CAD solids.
When should I use this skill?
The user asks for CAD, STEP/STP, build123d source, assemblies, mechanical features, or STL/3MF/GLB exports from CAD geometry.
What you get
Validated STEP compounds or assemblies plus optional STL, 3MF, or GLB exports and inspectable geometry references from the CAD workflow.

What is the primary output format?
STEP/STP is the primary CAD artifact; STL, 3MF, and native GLB are secondary exports from that geometry.
When should the skill be avoided?
Skip it for render-only art, CAM toolpaths, certification claims, or BIM unless CAD solids are also required.
What library maintains this skill?
It is part of earthtojake/text-to-cad, described in the repo README and skills/cad/SKILL.md.
