Free AI CAD Generator: Open Source Alternative to AutoCAD

Mô tả

Text-to-CAD is a free, open-source harness that gives AI coding agents like Claude Code and Codex the ability to generate real 3D CAD models from plain English descriptions. It exports to STEP, STL, 3MF, DXF, GLB, and URDF formats and includes a local browser-based CAD viewer for inspecting generated geometry. Everything runs on your machine — no backend, no cloud, no subscription.
