V6 can’t/doesn’t find an intersection between these two parts. They were created in V6. One surface is a fillet and the other is an Extrude Tapered surface from a simple curve. V5 and V4 both work as expected on these surfaces.
Somewhat off topic, I’m finding the object snaps in V6 don’t work as well as they did previously. Often, when working in a shaded view port, I can’t snap at the point I’m looking for. If I turn off shading and work in wire frame, it works normally. Any thoughts?
