Modeling Thick Finishes
Thicker finish materials such as tile, stone pavers, or terrazzo can be applied as unique floor
types and modeled where required. For large areas of finish such as a public atrium or airport
terminal, you can assign these materials within the layers of a floor assembly. When you need
to add smaller areas of thick floor finishes, there are two scenarios you may encounter: with a
depressed floor and without.
In areas such as bathrooms, a thick-set tile floor may require the structural slab to be
depressed in order to accommodate the thickness of the finish material. In Figure 13.20, the
main floor object has been cut with an opening at the inside face of the walls. Another floor has
been modeled with a negative offset value to accommodate the thickness of the tile material,
and the tile has been placed as a unique floor element.
