. Add to that, the free factor, and ease of use and it's a start in that direction.
There is actually solids (OBJ) and nurbs support via plugins, but I wouldn't really bother with that, as the app handles nurbs in a relatively unpredictable/uncontrollable fashion, and as monkeyfist said, gmax/3d studio max is not cad software
, that's why I recommended it as just something to experiment with. There is, however, a plugin called.........................let's see..............................................C NC TOOLKIT! (brain fart moment), for gmax/3dstudiomax, that can be used to generate simple 3 axis g-code from splines IIRC, but it's very crude and very inefficient code-wise. You can wind up with 10,000 lines of code to do something that really only requires 10 lines. Polylines being part of the problem. It can be fun to mess around with, though it seems very unlikely anyone here would make use of it.
here's an example of how inaccurate it would be to produce a part using a model produced in gmax. I just did these 2 models of a steering link for a rc18 I've got sitting here. Each took about the same amount of time, most of it was spent measuring (~under 10 minutes each). Can you see the difference (yeah, yeah, besides the diameter of the ball link holes
