HAH! Who should have known! It's already there! :D

Seams like max's ever so shitty NURBS already has the convertion methods (b-spline > swept NURBS > Poly surface) all I have to do is script it all for automation :P The results are perfect, and it can do different kinds of optimizations too (not really a good choice I'd say, since it would ruin the edgeflows)...

So I guess I just saved myself alot of work :)
