I have an issue with a parking garage. How do I set up the view range for a garage. From the north end of the floor to the south end changes 10'. The problem is that when I get everything on the south end of parking level 1 visible then everything on the north end of level 1 is not visible. If I change the view range to include everything on the north end of level 1 then it make everything that is on the level below on the south end visible. Any suggestions. I have attached a pic as an illustration.
