I'm aware, however there have been a couple efforts now to introduce CAD tooling into Blender.

I'm not suggesting that they are ready for professional use, just that I don't think the Autodesk moat is as deep as some might assume, and that if there was a concerted community effort Blender could accomplish those tasks.
