I need to wrap a a curved sketch all the way around a cylinder. Every time I try to do this I get the error message "the wrap feature cannot be created from intersecting or open contours". I have tried using equations as the dimensions in order to get the length of the sketch equal to the circumference of the circle but I have not had any luck.

Attached is what I have so far. Basically I need three concave parabolas evenly spaced around this cylinder. The ultimate goal is to remove everything above the sketch so that I am left with a cylinder with "three peaks".

Any ideas why I cannot create this wrap feature? Is there an easier way to do this?
