Claude Transforms Napkin Sketch into CAD Model in Under 10 Minutes
burhop · x · 2026-08-13
A developer shared an experiment using Claude for automated CAD modeling. He sketched a geometric part on a napkin and provided it to Claude along with instructions for dimensions, fillets, and holes.
Workflow Performance:
- Claude successfully deciphered the design intent and verified its understanding with a clarifying question.
- It then built the part in less than 10 minutes.
Technical Challenges & Breakthroughs:
- The experiment tested a topology naming layer. Some trouble occurred with fillets at the intersection of a diamond face and the web, but it was eventually resolved.
- Results show that agent management of naming via code is highly effective for common features, while others fall back to parametrically derived coordinate locations.
