hi,

so i looked into options some more and had a question. it looks like the 3d coat retop to the viacad subd to nurbs might be a simple way to get a cold shape fea model back to a nurbs model. so it would go stl to obj to nurbs. but i'm not sure what 3d coat version has the retopo. can you use the cheapest one for 3d printing. or do you need at least the hobby version or higher.

viacad has a lot of powerful features packed into a terrible interface. so i'm not too keen on getting viacad. so i may not even do this. but was curious about 3d coat. i watched some videos about the retopo and i think it would be easy and fast to do. the 3d coat website wasn't helpful in figuring out what each version does though.

note; i just recalled that didn't moi add obj to nurbs? is that going to be a v4 feature. if so then i wouldn't have to suffer with viacad.
