In the attached file I have two solids. The upper surface on the thin one (deck) is at the same level as some of the upper surface on the other one
When I add the two together I get a projection that sticks above the deck as shown in the image. In the image I have done BooleanUnion followed by MergeAllFaces. The last step just makes the anomaly stand out. It’s still there without it.
How can I get rid of this?
