Using Inserted 3D Data
Now that we have discussed using 2D reference data, we will show you how to use 3D model
data from other design software within your Revit project. There are many valid reasons for
modeling outside of the Revit environment, including software expertise, the availability of
content, and optimization of complex geometry. The following sections will explore some
situations in which model data can be shared between programs:
◆ ◆ Inserted data as a mass

◆ ◆ Inserted data as a face
◆ ◆ Inserted data as an object

Using CaD Data as a Mass
In Chapter 8, “Advanced Modeling and Massing,” you will learn more about harnessing the
impressive modeling toolset in the Revit conceptual massing environment; however, the fast
and flexible process of design may lead architects to a tool in which they have more expertise or
comfort. This type of massing design workflow is supported in the Revit environment under the
following conditions:

◆ ◆ Inserted model data requires solid geometry to calculate volume, surface area, and floor
area faces.
◆ ◆ Finely detailed complex geometry should be avoided because the Host By Face tools may
not be able to generate meaningful objects.
The following exercise creates an in-place mass by linking an external model—in this case, a
SketchUp model. Download the files c07-SKP-Mass.rvt, c07-Mass.skp, and c07-Mass-2.skp
from the book’s web page and follow these steps:
1. Open the project file c07-SKP-Mass.rvt. From the Massing & Site tab (if that tab isn’t
available, you can turn it on under the Application button ➢ Options ➢ User Interface),
select In-Place Mass from the Conceptual Mass panel.
2. Name the new mass family SKP Mass and click OK.
