[Trying drawing a sinelike shape on a cylinder][1] I am trying to draw the picture below. I tried using boolean modifier on the cylinder but, I couldn't create an object that would like on the picture below. Any tips on how I can remove a shape from my cylinder that looks like on the picture below?
