    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?

    The real question is how big around is your object, and what material are you designing for? 16 faces on a 1mm post may seem nicely circular, whereas 2000 faces on a 10cm surface may still seem faceted.

    I have a bit more of a writeup here about it..

    thank a lot Stonysmith. I'll just go for the maximum 200 sides, this should hopefully do it for such a small object as a ring.
