Revit :: 3D View Showing Floor Outline On Exterior Walls?

I am creating a two-storey single-family house.  The exterior wall assembly is Core Boundary, 3/8" Stucco (we apply a Stucco material to our Sheathing so in Section we aren't showing a finish material on the exterior), 5 1/2" <By Category> (our studs), Core Boundary, Air Barrier, 1/2" Gypsum Wall Board.  We draw the floor system to the face of our studs and extend our walls to the bottom of the floor system, then when we join geometry the floor cuts out the wall leaving only the wall sheathing extending to the face of our floor system.
 
My problem is when I create a 3D perspective view with the camera my floor system is showing through the walls.  It seems to thin out/disappear the larger the perspective view is on the page, but I can only make it so big on C-size page.
 
Is there a way to hide what Revit shows detailed behind the face of a material?(I tried hiding the floor system in my perspective view but it stills shows the floor outline, I'm assuming because it is being cut out of the assembly).
