VibeCAD

VibeCAD provides Claude Code agents with skills to create parametric 3D models, render visualizations, and optimize designs using Build123D—a Python CAD library with algebra-style syntax. It includes tools for model comparison using IoU and Dice metrics, GLB rendering for visual verification, and glTF optimization with compression and mesh simplification. The library integrates threaded fasteners, pipes, flanges, bearings, and gear generation (spur, helical, bevel, planetary, cycloid) through bd_warehouse and gggears. Agents can export designs to GLB, STL, and STEP formats, enabling automated design workflows without manual CAD software interaction.

Add the VibeCAD marketplace to Claude Code with `/plugin marketplace add raymondweitekamp/VibeCAD`, then install plugins like build123d, render-glb, and gltf-transform. Invoke skills using the format `plugin-name:skill-name` (e.g., `build123d:build123d` or `render-glb:render-glb`). Claude automatically triggers skills for CAD modeling, rendering, and optimization tasks, or you can explicitly load them.
