This one is difficult to explain so I took a picture. I need to duplicate a mold (male). I'm thinking the original was done in Pro/e because of the way it is drafted. Is it possible to draft from the top arc down to the top plane? This would give me the curve at the bottom that you see. I believe in Pro you could select the top arc and the resulting draft would fall away at the specified angle. I tried surfaces and such but it's not exact and I'm not a big fan of mixing surfaces in with solids if I dont have to.

See attachments- Thanks
