However you decide to create a fixture, it is important to build your fixture
family so that when it is placed in a model, it can be associated with a Space
object in order to provide the desired engineering data from calculations. A
light fixture that is not inside or touching a Space object does not generate
anaverageestimatedilluminationforthatSpaceobject.

group of fixtures placed higher than the upper limit of an engineering Space
object; therefore, there is no illumination calculated for the Space object.

Fixtures outside the limits of a Space object
One way to remedy this is to use the Room Calculation Point that can be
added to families such as light fixtures. This point allows you to associate a
light fixture with a space even though the fixture is not within the bounds of
the space. To add a Room Calculation Point to a light fixture family, select
the box in the Family Category And Parameters dialog box.
The point can be located anywhere in the family by dragging it along either
axis, as shown in
Figure 20.10
. The location is set in the family and cannot
be modified in the project.
