Solidworks, Creo, AutoCAD, Fusion, etc., can all take their bug ridden unoptimized single threaded rent-seeking monstrosities and stick em where the sun don't shine.
Seriously - if anyone wants to create an absolutely world-changing piece of software, start working on a new CAD kernel that takes the last 50 years of computer science advances into account, because none of the entrenched industry standards have done so. Don't worry about having to provide customer service, because none of the entrenched industry standards worry about that either.
And no - while openCascade and solvespace are impressive, they aren't fully capable, nor do they start from a modern foundation.
