Hi, i'm using sketchup to build a ring. How many sides do you need so that a circle is actually felt and seen like a circle? The default setting in sketchup is 24 sides, which looks not really round. 200 sides makes my pc really slow if i turn the circle into a 3d object (with the follow me tool) Do i need more or is 200 enough? Or are there other techniques to make things round?
