>when there are free open-source alternatives like OpenSCAD.

As much as I agree with the fact that they should have built that tool for free open-source alternatives first and foremost, OpenSCAD is not the right choice.

OpenSCAD is a fantastic tool to whip together a box for your hobby electronics project, but doing serious professional CAD models ... it's just not in the same league as fusion, onshape, and freecad (as hideous as FreeCAD's UI may be).
