PartMode
PartMode is open-source parametric 3D CAD that runs in the browser and is built to be driven by both people and AI agents. You can create multi-part designs and assemblies with lofts, sweeps and mates, browse a shared parts library, and export to STEP, STL, AMF or 3MF, while a command-line interface lets agents make permissioned changes. No account is needed.
