Blender isn't really made for CAD at all, although there are few CAD plugins. It's more for artistic modelling like MAYA or Cinema3D.

There already are LLM plugins for Blenders and prompt integration for model generation, rigging and co.

MAYA has extensive NURBS tools, which means it can import and export CAD data natively. While Blender does support basic NURBS geometry, it lacks tooling to fully support it.

If the idea is to support Blender for use with “Digital Twins” or “World Models” then the first step is to start with accurate geometry. Anything less is slop.
