A good example of a light fixture using a nested annotation symbol is an
exit light. These fixtures are commonly shown on construction documents

or direction arrows that are on the fixture.
Figure 20.22
shows an exit light
family in both plan and 3D views. Notice that a symbol is used to represent
the fixture in ceiling plan view and that a filled region within the symbol
indicates the location of the face of the fixture.

Creating this type of functionality is easily achieved by using a nested

contains lines and filled regions whose visibility is controlled by Yes/No
parameters.
