SOMA

SOMA: Desktop app for designing parametric 3D models in CadQuery together with a coding agent.

SOMA is a desktop application designed for creating parametric 3D models using a coding agent. Users describe or sketch what they need, and the agent writes Python code using CadQuery, which SOMA builds and renders in real time. It is built for makers and tinkerers who need custom parts like cases, brackets, or mounts without spending hours inside traditional CAD software. The app integrates with any CLI agent that reads files and runs commands, such as Claude Code, OpenCode, Codex CLI, or Gemini CLI. SOMA supplies a command line tool and project rules to guide the agent, while users retain their own subscriptions and model choices. Key capabilities include visual inspection, measurement, drawing on views, parameter adjustments, history tracking, rule sets for manufacturing, and analysis tools.
