In model setup I have selected 2 floors and 0 basements ,the layers of mod- foundation,mod slab-1,mod-floor-1,mod-slab-2,mod floor 2,mod-roof are created when giving heights in next step.I have created each floor in the appropriate layer using wall tool and the foundation/slab by extruding a solid because of this it only ables one layer to render while the rest is in wireframe.makes it difficult to understand the creation as a whole. I assumed there would be a way to render all layers? It also creates difficulties when creating a sectional perspective to render all layers.
Thanks
