The intersection of buildings is only considered on the XY axis, though, which is obviously 2-dimensional. Two buildings project XY axes out from their origins and these axes are considered as being on the same Z-level for the purposes of obstruction, as I understand it. Regardless of the fact that the planet surface is curved and non-smooth, the overlap checks cannot be called 3-dimensional; that is all I'm noting.

In any case, I'm feeling happier since the suggestion of an attempt at a more realistic full-intersection check in future; but I would to like to ask that, if that actually proves impossible once you have tried it, we turn and continue to look at the problem from other angles. Obviously, that is not a question for today.
