Key point

The tool uses a CLI to let the AI agent measure distances, check collisions, and run FEM to self-verify generated 3D models.

SOMA is a free, GPL-licensed open-source application that enables AI agents to perform CAD tasks by writing Python code with CadQuery.
The system allows the AI to self-verify results by building models, measuring distances, checking for collisions, running FEM, and rendering images.
Supports integration with Claude Code, Codex, OpenCode, and Gemini CLI, utilizing the user's existing subscription without requiring extra API keys.
Features include per-model skills for 3D printing, CNC, and sheet metal, plus a history system to revert errors; demonstrated on a CNC mill assembly with 118 parts.
