Hi all 
  
I'm doing a simple isometric campus map for a client and somehow I got a section with roofs on them. I don't need them b/c we need to look down into the building (dollhouse type view) I tried deleting some walls but the roofs are still there, now just crazy cabanas. Can anyone help, how do i get rid of these floating roofs? (screen shots attached)
