Codex feature request: natural-language CAD design for FreeCAD/SolidWorks

I would like Codex to eventually support CAD and invention design workflows. For example, I would like to be able to tell Codex: “I want to build this invention in FreeCAD or SolidWorks,” then guide it with words while Codex creates or modifies the design. The ideal workflow would let users describe parts, dimensions, mechanisms, movement, materials, and constraints in plain language. Codex could then generate the CAD model, update it, and explain what changed. This would be useful for inventors, product designers, engineers, and people who have strong ideas but are not advanced CAD users. It would also be helpful if Codex could: * generate FreeCAD scripts or SolidWorks-compatible files * revise dimensions from user instructions * create assemblies from multiple parts * check for basic mechanical conflicts * export files for prototyping This could make Codex useful for real-world invention development, not just software development.
