Cad Studio
Cad Studio is a native macOS CAD studio that generates 3D printable models and technical drawings from text descriptions.
CAD Studio is a native macOS application that turns text descriptions into printable 3D models and ISO technical drawings. Users describe a part or mechanism in chat, and an integrated coding agent powered by Claude Code or Codex writes and executes parametric build123d Python scripts. The app features a live 3D viewer, physics simulation, multi-part management, a floating parameter panel, and version history. It supports attaching reference images, sketches, PDFs, and STEP or STL files to the chat. Outputs include STEP, 3MF, STL, PDF drawings, and ZIP files. It is designed for engineers, makers, and designers who want to build mechanical parts using natural language and AI agents.
