There are two problems with this: 1. I would have to create bounding boxes for every object on the screen, because you never know if some weird part 10 inches away has a 10-inch clearance requirement. 2. Small parts, like vias, are able to be completely contained within the bounding box - so checking for intersections won't help me.
