Text-to-CAD | Hacker News

Hacker News users discussed early text-to-CAD workflows using Claude and other local models to generate or repair OpenSCAD models from text and screenshots.

The thread compared these experiments with newer CAD systems, FreeCAD, and AI-driven modeling tools like zoo.dev and BRep-based approaches.

Commenters saw real promise for 3D-printing and iterative design, but noted major limits in spatial reasoning and keeping multi-part assemblies consistent.

Overall, the discussion suggested AI can already help with some CAD automation, but complex geometric modeling is still a hard problem.
