A YC startup open-sourced text-to-CAD — an embedded engineer called the V8 demo 'a lie' (github.com)
Adam's open-source core, CADAM, wraps Claude (with OpenAI/OpenRouter fallback) around OpenSCAD compiled to WebAssembly: describe a part, get parametric code with auto-generated sliders. Parameter tweaks skip the LLM via a regex edit on the source.
The benchmarks lead with a V8 engine and a turbofan. "That's a lie," wrote an embedded engineer — "a bunch of boxes with no fasteners to hold them together." Another user fed it a real part number and got wrong pitch, wrong pin positions, missing pins.
