subdiv makes not a circle out of a square???

hi

as you can see the left is a square and in my theory the subdiv
should make a perfect circle when subdivsurf is turned on.

anybody knows why this does not work?

In my theory, it should not. Your theory seems to be wrong :wink:

Google for “catmull-clark” and find out why it’s not round.
