Text-to-CAD

Text-to-CAD is an open-source library that gives AI agents CAD capabilities to generate models, drawings, and files.

Text-to-CAD is an open-source tool that gives AI agents focused workflows for computer-aided design, fabrication, robot description files, simulation, and local review. It creates and edits CAD models from plain-language or image requests, with STEP as the main output and options to export to STL, 3MF, and GLB. The software also finds off-the-shelf STEP parts, generates dimensioned engineering drawings as PDFs, creates 2D DXF drawings, writes robot structure files, and builds simulator models and worlds. Additionally, it checks DXF and STEP files for SendCutSend, measures mesh printability, reviews parts for manufacturing, slices models into G-code, and sends prints to Bambu Lab printers. It is designed for developers and engineers who want to integrate CAD capabilities into AI agents like Codex and Claude Code.
