Face-hosted family for a wall-mounted light
Face-hosted families have a Default Elevation parameter used when the
family is placed on a vertical face. When they are placed into a model
on a vertical face, the Elevation Instance Parameter becomes active and
is used to set the mounting height. The Default Elevation parameter is
simply a starting point until an elevation is assigned after the placement
of the family. You can set the Default Elevation within the family file to
any value that you want for the mounting height when the fixture is first
placed into your project, but because of the functionality of the Properties
palette, you may need to input a value during initial placement. It is a type
parameter, so you can use it to define different family types if desired. In
the project environment, the Elevation parameter is active only when the
family is placed on a vertical host. When a face-hosted family is placed on
a horizontal host, the Elevation parameter is inactive and cannot be edited.
Figure 20.7
shows a wall-mounted light that was placed into the model at an
elevation of 4′-0″ (Default Elevation) and then given a mounting height of
7′-6″ (Elevation) after placement.
