The problem here is that it is a commercial program, which was made freely available, with the explicit intent of taking the oxygen away from other free, and esp. opensource programs.
Yes, I’m a bit hypocritical on this since I work for a company which makes Carbide Create freely available, but given that the latter is mostly marketing for the machines, I believe this may be excused.
FreeCAD has seen remarkable advances of late, and I’m seriously considering it for developing the next round of parametric designs which I work up. Unless of course, I can manage to cobble together a system which allows one to use OpenSCAD as a front-end, and yet which elegantly generates files for cutting in some fashion.
For basic things which may be represented in 2D, OpenSCAD works pretty well on its own:
Unfortunately, things are far more difficult for anything which requires any sort of 3D modeling — still working on the files for:
