Hi,

I'm looking to pattern a revolved cut (in this case a groove) up a curved surface of a revolved boss.

I've attached a model of something similar, and you'll notice that I've already done the first cut. I am trying to avoid having to sketch all of the cuts individually, but I haven't found a way to make it pattern properly and have the repeated revolved cut be the same depth the whole way around the model.

I've tried a curve driven pattern, but the cut only follows one curve so it is never the proper depth all around the boss, as shown below.

Thanks in advance for your help,

Matt
