Yeah, I know exactly what you mean :-/ > We do not have any overlap issues in SolidWorks. Okay. Then it's strictly the tessellation process itself. I believe there are a couple of tolerance parameters (linear and angular) which you can set when you do the STL export. The smaller you make those, the closer you'll get to the true cylindrical shapes. At the same time, the output files become much bigger (because there are N^3/2 more little polygons), and your geometry initialization will take longer. Good luck! -- Mike Kelsey
