Yes I found that tutorial as well, but it does not create a symmetric sphere or symmetric dimples in the golf ball.
Try it.
I have tried a chamfer width from .335 all the way to .447 and the dimples are just not symmetrical.
That is what lead me to post the challenge. I want to create a golf ball that has symmetrical dimples and of course is also round.
