Sorry about that, as I'm a graphic artist I was talking about the
field of artistic modelling (mainly organic stuff). Of course I know
that many other ppl use povray to do scientific visualization, cad,
architectural stuff etc, but I think that those fields are already
covered and that povray really lacks only in that one (I don't know
really, of course I know more of my field). Again, sorry...

Mhm... Too many...

I don't know this cad system (is that a cad?). The only 3d modelling
program that is more cad-ish that I use is rhinoceros (and I really
like it too)
