I am playing around with threads and screws, but I am beyond frustrated with something I have been able to do in the past, but not today apparently.
I have created a plane tangent to the surface of a cylinder, and I want to cut a closed profile away from the rounded surface, along a helix. I am making a screw here. For some reason, Solidworks does not believe that I have a closed profile. Any suggestions?
By the way, while playing with it earlier, I was able to do it on this same sketch. I was originally extruding off of the surface, but decided to mirror my sketch in order to cut away from the surface.
If I try to select the sketch profile line by line, I can select all entities except for the arc.
