Meshy generates 3D models from text or images, so it makes 3D shapes like SOMA does but from a description rather than CAD code, with a printability check and auto-repair.

SOMA
SOMA is an open-source desktop app where a coding agent writes CadQuery code that SOMA builds into a 3D model.
What SOMA does
Users describe a part to a coding agent, which writes it as CadQuery Python code that the app builds into a 3D model. The app lets users measure, mark up and adjust the model and then export it to common CAD and printing formats.
Built for
- Designers and makers who want to model parts with a coding agent
Key features
- Agent writes models as Python CadQuery code
- Rebuilds the 3D model on every change
- Mark up views with arrows and notes for the agent
- Exact measurement of faces, edges and distances
- Adjustable parameters without editing code
- Timeline of agent changes with version restore
- Exploded assembly views with a slider
- Motion animation scripts with video rendering
- Printing checks and CalculiX finite element analysis
- Technical drawings and export to STEP, STL, 3MF and more
Pros
Pros
- The code behind each model stays available for manual edits.
- Works with several existing CLI coding agents that the user installs and signs in to.
- Source code is published on GitHub under an open license.

Claude Code is an agentic coding tool that edits files and runs commands, the kind of coding agent SOMA relies on to write its CadQuery models, though it is not a CAD app itself.
