When doing F6 with show edges enabled there seem to be missing edges. For example here is a tube unioned with a flat plate. [image: image.png] Why is there not a circle of edges where the tube intersects the top surface of the plate? Similarly, looking into the tube there are missing edges. [image: image.png]

To answer my own questions, I think I have probably asked it before. The missing edges are drawn on the inside. Can this be fixed?

Is this an aliasing effect? Does moving the object around, and changing viewport make any difference?

No, it's consistent. It seems the concave edges are drawn on the wrong side, or at the wrong time.
