Alibre Atom3d? I too have failed at freecad, and am a fusion360 exile. The old school "purchase your software" lifetime license model and the fact that I've not needed the "advanced 3d modeling" feature of Design pro for my 3d printing/etc needs has kept me fairly happy with it. They have a free/hobbyist version, but I just paid them for the basic atom3d (when it went on sale??) a while back.
