That's great! I can stop reading about Harris operators. I totally agree
about orthogonal snapping.
Orthogonal snapping would be useful more generally - do any of the editors
have this feature for manually drawn buildings etc.?

Hi again, thanks for the comments.
How well would this scale up to the whole country? (!! Not automatically
