Someone correct me if I'm mistaken but don't CAD programs rely on a geometric modeling kernel? From what I understand this part is incredibly hard to get right and the best implementations are proprietary. No LLM is going to be able to get to that level anytime soon.

Sounds like GP is just in need for a G-Code to DXF converter when they mention "fringe stuff, cnc machine files from the 80's/90's" as answer to a sibling comment, though.

There are great FOSS CAD tools available nowadays (LibreCAD, FreeCAD, OpenSCAD etc.), especially for people who only need 2% of a feature set. But then again, I doubt that GP is really in need of a CAD software, or even writing one with the help of Gemini.
