I've seem to run into a new problem that I never had before. The issue is that the slabs that I am copying from one floor to the next are not showing up in 3D only on the floors where the slabs were copied to. On top of that, all of the walls that intersect the slabs are missing material where the slabs pass through them. It's as if the slabs have a clear glass surface finish and thus are invisible. I have checked and the surfaces of the 3D model are set to "concrete - Structural" for all sides. I've tried everything I can think of without results. All help is appreciated.
