Imagine a cylinder, but cut in half so that the cross section of the object looks like a half-moon. I am trying to bore holes (fastener holes, couterbores, etc) into the curved surface of the half-cylinder, but (of course) perpendicular to its flat plane.
I have tried 2D sketch on the flat plane, an offset 2D sketch (both above the curved surface and intersecting it), and a 3D sketch, but I cannot get the holes to bore into the surface using the Hole Wizard. I either get an error or the holes bore from the other (flat) side, which is not the side I want.
What is the easiest way to get what I want? Any help? Thanks very much,
Curry
