I see that hread had to do with large tooth counts in a gt5-2 causing the stl file to look bad. What usage are you wondering about?
If you need a good dxf, the dxf should be good out of GM, but if you need an STL of one, then save a GM project , load it into GT
and it will reextrude to a high resolutio n STL.
It all depends on the method youll use to make it, but Im assuming we're talking either dxf or STL model?
