I have a problem surface here maybe someone can help me with.
Both top and bottom surfaces here are identical, save for arbitrarily moving one point in XZ (circled in red), which shouldn’t have any effect you would think? Top example shows that it intersects and trims correctly with the surface on xz plane. Bottom is the untouched surface that won’t correctly intersect and trim.
I have trimmed most of the surface away, just to protect client’s data but that doesn’t seem to have affected the behavior.
