3.
If necessary, orbit the 3D view so that you can see the bottom of the lowest floor slab. Pick
all four bottom edges of the floor slab at the level named Ground.
4.
Activate the view Section 1 and you will see the slab edge applied to and joined with the
floor, as shown in Figure 13.11.
Remember that the material in the slab edge type must match the material in the floor
type properties for the geometry to join properly.

Making early Design Models
When we first started implementing revit in early phases of the design, the need to emulate draft-
ing methods was readily apparent. as a design idea for a building was formulated, we would usu-
ally make some generic assumptions about more complex systems in order to make the overall
design intent as clear as possible. how do you translate this so-called fuzzy design into a building
information modeling process?
to bridge the gap between fuzzy design and a highly accurate model, we created a single floor type
that contained assumptions not only for the floor but for the structure and ceiling assembly below.
This larger assembly gives a graphic emphasis to building sections without the burden of modeling
three different systems before they are close to being resolved. The design floor type also gave us the
opportunity to create custom slab edges that are voids instead of solids—voids that approximate
a design for ceiling shade pockets or other interface conditions.
Creating a Custom Floor edge
You can apply a great deal of flexibility to a floor assembly in early design. As we described
previously, you can create a floor for early design phases that accommodates the floor, structure,
plenum, and ceiling in a single floor type. You can also apply a customized edge to this type of
assembly for more creative soffit conditions at exterior walls, as shown in Figure 13.12.
