Selecting different elements in different levels.

[Anonymous]

I want to select the exterior wall in level 2 and the slabs that close it, slab on top of level 1 (floor of level 2) and slab on top level 2. I can select the wall and then the slab on top, and then show them in 3d. But how can I make to select the slab on top of level 1 to show the 3 elements on #D view?

If the slabs are in different storeys then you need to set their floor plan display to 'Show one storey up' or 'Show one storey down'.
Then you will be able to select the walls and slabs all from one storey.
You may need to use the TAB key to cycle through overlapping selections.

Or place a all-storey (fat) marquee and view in 3D.
Then select the walls and slabs and then 'view selected in 3D' so only the selected items show.
