Ok so it seems there was no solution, so I made the pipe part into a rectangle and then mastercam was able to identify drill locations. Kind of a dumb way to have to locate drill hopes, but I guess that's the way it goes.

So I have a pipe part, made in solidworks, that has holes cut in it. In Mastercam I can see the holes, and I can create all the surfaces from the solids. I can also create the arcs from the surfaces. But the problem I seem to be having is being able to cut the holes. Mastercam does not seem to bring in the centerpoint for holes cut in the pipe.. perhaps because the pipe is not a flat surface? Normally I select the hole positions from these centerpoints, but apparently since the surface is not flat, its a pipe, the hole center point does not show up. So what I need to have is a drill centerpoint to show up. How can I turn these on? So I've tried to do a "masc on arc" these holes, but again, the surface is a surface of a pipe, and this seems to confuse mastercam. Anyone have ideas on how to do solve this problem?
