Hi, despite carefully clicking on the corner part then selecting my curved cutting surface, Boolean Difference removes the larger part of the base.
I wanted a 5mm radiused corner, failed with a sweep surface, those pesky feathered surfaces again. then tried fillet, and decided to use the failure there to act as a cutting surface, at least it cuts, but the wrong part.
Just how does one create a surface which is bound to be coincident as it goes tangent, for cutting away such parts, especially if I wanted an elipse section. there is no elipse fillet, wish there was.
