Modeling Floor Finishes 553

Figure 13.20
The thick tile fin-
ish and depressed
slab are modeled as
separate elements.

If you don’t need a finish but just a slab depression, you can create it with an in-place void
extrusion. Select the Architecture tab in the ribbon and click Component ➢ Model In-Place.
Choose the Floors category and create a void extrusion where you need a slab depression.
Remember to use the Cut Geometry tool to cut the void from the floor before finishing the
family. As an alternative, you can create a floor-based generic family that contains a parametric
void extrusion. You can download the file c13-Slab-Depression.rfa as an example of this
type of family from the book’s companion website.
Finally, if the structural requirements allow a thick finish to be applied to a floor without
dropping the structural slab, a finish floor element can be modeled directly in place within
the structural slab. As shown in Figure 13.21, the tile floor has been graphically embedded in the
structural floor using the Join Geometry tool. To do this, click the Modify tab in the ribbon
and click Join Geometry. Be sure to pick the finish floor before the structural floor or you will
get an error.

ish floor has been
joined with the
structural floor.
