Notice it is now selected in the 3D view to the side. These views you
have open are mere representations of the model from that perspective.
Each view of the model can have its own independent view settings.
You are at a good point now to save the file. And this brings the book to a good
point to discuss the different file types, and their association to the BIM model.
File Types and Families
Revit Architecture has a somewhat unique way in which it saves files and uti-
lizes different file types to build a BIM model. To learn how and why Revit has
chosen these methods, follow along with these steps.
1. Click the save icon (see Figure 1.50).
FIGURE 1.50: The traditional save icon will bring up the Save As dialog if
the file has never been saved.
2. In the Save As dialog, click the Options button in the lower-right cor-
ner (see Figure 1.51).
FIGURE 1.51: The Options button in the Save As dialog will allow you to
make some choices in how the file is saved.
3. In the File Save Options dialog, you will see at the top a place where
you can specify the number of backups, as shown in Figure 1.52. Set
this value to 1.
The reason Revit does this is because, when you click the save icon,
Revit actually duplicates the file. It will simply add a suffix of “001” to
the end of the filename. Each time you click the save icon, Revit will
record this save and add another file called “002,” leaving the “001”
intact. The default is to do this three times before it starts replacing
the 001, 002, and 003 with the three most current files.
