4. Under the Preview section, you can specify which view this fi le will be
previewed in. I like to keep it as the active view. That way, I can get an
idea if the fi le is up-to-date based on the state of the view. Click OK.

stands for “No Experience Required.”) Of course, you can name the fi le
anything you wish, or you can even just do your own project using the
steps and examples from the book as a guideline.

specify the number of backups and the view for the preview.
Now that you have experience adding components to the model, it is time to
investigate exactly what we are adding here. Each component is a member of
what Revit calls a family.
UNDERSTANDING THE REVIT ARCHITECTURE FILE (.rvt)
The extension for a Revit Architecture file is .rvt. There are three separate
Revit applications: Revit Architecture, Revit Structure, and Revit MEP. All
three Revits share the same .rvt file extension. You can open a Revit file
produced in any of these three applications directly. You do not need object
enablers to read items that do not pertain to that discipline.

As mentioned earlier, a Revit model is based on a compilation of items called
families. There are two types of families: system families and hosted families. A
