The attached file contains two closed surfaces. When I try to boolean union them, I get lots of non-manifold edges. The mating areas are on close surface is flat and should be exactly Z=16.675" on both sides.
Apparently, the flat bottom surface of the top part is not being adjusted to match the shape of the bottom when they are joined.
Why is that?
How does one correct?
