I was an intermediate user of VW2002 years go, now trying to get back into the program. I don't understand what's happening in my Top/Plan view: I drew a slabless floor plan. Everything was fine in 2D and 3D. Then I added a slab bounded to the outside wall edges. Everything including the slab, is correct in 3D, but doors & windows, shapes etc., disappear in the Top/Plan view. Remove the slab and they reappear. It's as if the slab is sitting on top, but it's not. I'm sure it's something simple that I'm being thick about or have forgotten, but so far I have not found the resolution. Any help is greatly appreciated! Thanks!
