text-to-cad turns parametric CAD into a local agent skill: plain language or an image becomes a STEP model with STL/3MF/GLB exports, plus DFM review, dimensioned drawings, URDF/SRDF/SDF robot descriptions and 3D printing, sheet metal and CNC integrations. Kernel is build123d on OCP; the shape is twelve skills plus the cadgen engine and a local CAD Viewer. MIT, about 20.6k stars.
David Bar's ten checkers for agentic CAD - spec, motion, geometry, edge, manufacturability, fastener, hole, picture, accepted-problems and test-the-checkers - written in Python on build123d and run after every model update.
