Im new to cad drawings, but I've had plenty of experience with 3d modeling.
In 3d modeling in a non-cad setting, I would suppose that most everything you create is considered art, and therefore has intellectual property protection.
On the other-hand, CAD drawings are of some useful object, are they still granted the same protection?
What kind of intellectual property protection can you expect on CADs, and what is blatantly illegal/ companies go to lengths to prevent you from doing>?
