What exactly is the rule for the number of sides you can have on a circle in sketchup if you are printing with a 3d printer and want precise and fine results. I am using a high end printer to delivery fine results, fusion f400 with a. .4mm nozzle. So the circle needs to be precise as I will be putting close to the diameter cylinders in the holes. For this application I will be using 12mm diameter holes, but latter it will change. Hence a good general rule would help. I was thinking about 144 sides but maybe that is CRAZY to much, or perhaps I could even go more. I really have no idea.
