The circles also look a bit jagged (as if a polygon) rather than smooth.
The discrepancy is only in the graphical representation: OpenGL cannot render curves - so curves have to be subdivided into straight line segments. You can increase the number of sub-segments for the graphical representation with the "Geometry.NumSubEdges" option (in the GUI : Tools->Options->Geometry->Aspect->Curve subdivisions). > > I did have a smooth nice mesh earlier but I reduced the overall dimensions a > bit and this happened and now it won't go back to the same even if I use the > original script.
