Thanks for at least trying it out, maybe they will heed your advice. It
looks like Art of Illusion and Wings are broadly, like Blender, from the
"3D Graphics" category of software tools:
There is a lot of overlap between these programs and the ones that identify
as mechanical CAD, and I have a hard time keeping track of where one ends
and the other begins. My impression is that for this type of program, the
open source options are already at that GIMP vs Photoshop level, but I'm
only a novice at any of these so I can't really say.
I think the conventional wisdom is that if you are going to make something
precise, machine parts, and complex assemblies, mechanical CAD purposed
programs have a big advantage. If you want to 3D print organic shapes,
mock up sculptural forms, or render computer graphics, then the 3D Graphics
programs are often the best tools.
That said, today, if you really need to get something done with mechanical
CAD, you are probably going to have to get access to a conventional
proprietary program, which is especially obnoxious for someone who runs
MacOS. I'd be happy to show you Solidworks and free-cad at Noisebridge
some time, which may help you decide whether you want to put effort into
the build process. It does seem that, if you generated binaries for your
version of the Mac SDK and made them available for download, it would be a
great service to other people like you!
