Re: Simple way of making Golf Ball with Solidworks!

If you look at the link it seems to be what they did on some golf
balls. You cannot project a sketch, but you can get points from a
sketch to project onto a surface. Very tedious, but doable.

yes, tedious, but fascinating. Modeling the ball is dull - just
patterning/mirroring a bunch of revolved cuts (yawn, and yes Cliff, I
tried it).
But trying to project an icosehedron on a sphere was quite educational.
One thing that caught me up in a big way was that, though you can
split a 2D triangle up into four identical 2D triangles, it doesn't
work that way on an equalaterial triangle on the face of the sphere
(which I didn't catch until wasting a fair amount of time)! The
phenomenon even shows up on the wikepedia (or whatever the reference
was that you posted) picture - if you look closely, the small triangles
(with the smaller dimples) aren't equalateral, and the spacing between
the dimples requires a little adjustment.
There were some otehr fun geoemtry tricks and gimmicks to pull this one
out, but its really about the icosehedron.

So, thanks for the reference info, Paul. Not a bad way to burn time on
a plane.
