Thank you Carlosan. This I feel would be a great feature when trying to make a perfect circle retopo. Maybe having it perfectly equilateral is not needed. I am not sure. Since these retopos are for game models maybe no one will see a slightly wobbly circular shape. Eyeballing it by hand is pretty close btw. This also maybe impossible to do since the verts are going to snap to the surface therefore breaking the equilateral edges. I thought about importing the retopo into 3dsmax and making the shape I need, then attach it and export it back into 3D Coat. Then try to place the verts without buggering the thing up LOL.
