Changed my settings here. DMs should work.

This is the start of a bigger push. Over the coming weeks we'll be releasing a proper benchmark for AI-driven CAD generation, along with tooling to support it. DM me if you want to be part of it.

Can frontier language models turn a technical drawing into real CAD? We ran the experiment. Gemini 3.1 Pro, Claude Opus 4.7, and GPT-5.4 got a set of technical drawings and were asked to reproduce a part as a valid 3D CAD model. Still a far way to go, but clearly a sign of life.

Each model had access to the build123d Python library, with rendered feedback and a B-rep validation routine running after every iteration, all inside a 1M-token context window to iterate in a loop. We ran all three on default reasoning settings.
