So i need to cut slots into a cylindrical piece. I completed a similar operation yesterday with regular holes but this part requires slots cut perpendicular to the surface around the cylinder. Hole Wizard does not allow the 3D Sketch option with slots and I cannot choose a curved surface to cut slots into. I have created a secondary sketch to coincident the slots to but I cannot select the surface like I can with holes. Picture shows partly what I am trying to accomplish but with a hole instead of a slot.
