The problem with a sweep is getting the right trajectory... I'm wondering if this wouldn't need some way to wrap a 2D sketch on a surface. If a curve could be wrapped on a cylinder that would provide the path.

There's been a recent topic where a BSpline used as path produced a non-smooth sweep, but I can't remember what it was ATM...
Wasn't that involving the sweeping, extruding and lofting of airfoils made with a Bspline? That's the one I'm remembering, mostly because I was involved in it. I do remember myself taking note that OCE 6.7 was doing a much better job with them than previous versions. It was stated in their release notes that it had received some love from the developers. Having your tessellation knocked back to something like .02 or so makes for a much smoother surface than the default 0.5. That setting in

I'v gone at this 4 or 5 ways this evening trying to get 3 hills and valleys. tanderson69 did a nice job on the bow spring washer with the CSG approach and the "S" shape wave spring is easy enough, and belleville springs are a no brainer. But that 3x3 wave... I was half expecting you to come up with some clever way and posting something like - "Here- that ain't so hard". Guess it kind of is.
At least I don't feel so bad now, not getting it nailed down.

on me otherwise.
