Modifying Families - Autodesk Revit Architecture 2015 Essentials - page 141

Let's look at another example of how the detail level controls the
visibility of families:
6. Open the elevation view named Cabinet. This view displays a cabinet
family with the other objects hidden in the view.
7. The detail level of the view is currently set to Coarse. Change the
detail level from Coarse to Medium and notice what happens. You
now see the cabinet panels and swing lines in the view (Figure 6.5).

8. Change the detail level from Medium to Fine and note what hap-
pens again. You now see the cabinet hardware that was not visible in
Coarse or Medium detail (Figure 6.6).
