I am constructing a 3 x 8 foot Somalia diorama, and I need to build 15 buildings with interiors. How can I construct a 3 or more-story building and still make it so you can see what's going on on every floor? I can't leave a whole wall off. I need all four sides. I could do only partial floors, because some of it should look like ruins, but some of the buldings aren't quite destroyed, and I don't want it to be confusing as to what floors are destroyed and which ones are cut so you can see through them. Cut the undestroyed floors at a straight angle? Even so, layered partial floors still blocks your view of the bottom floor.
