Hello all.

What should be number of splits for any circular pattern? Is there any equation to calculate? For example, for archimedes spiral how many splits need to be done for successful o-grid? Solid model has no any point or surface part inside because I draw it with equation drawer.

what are you trying to achieve? I wouldn't even try to mesh a spiral with a structured mesh...
