Hi @John_Brock i was more wondering why we have no options like regular offset, smooth or sharp or round. This is for both Windows & Mac versions.
I could explode or split my curves, then delete the fillet or corner , extend curve on surface and then trim where they meet to get a sharp corner. But it would be nice if Rhino gave us that option for OffsetCruveOnSurface.
