Summary
This is an open source harness that lets Claude Code and other AI coding agents generate 3D CAD models from text prompts using build123d and OpenCascade. You describe a part, the agent writes Python scripts in a models/ directory, and you get STEP, STL, GLB, and URDF exports along with a local React viewer at localhost:4178. The workflow is source controlled geometry: all models live as Python files you can version, edit, and regenerate. The viewer gives you @cad[...] references you can paste back into prompts for precise follow-up edits like "add a countersunk hole here." Built by ara.so, this is useful if you want programmatic CAD without opening Fusion or SolidWorks, especially for parametric parts, assemblies, or robot descriptions.
