Project Parameters
The only way to add a parameter to a system family is to add it by creating a
project parameter
. This allows you to customize the information you want
from elements within the model. Space objects can be given a lot of useful
data to help make design decisions and to analyze the model performance.
Project parameters make it possible to add this data to spaces and other
elements that cannot be physically edited.
You can add a project parameter by clicking the Project Parameters button
on the Manage tab. In the Project Parameters dialog box, you can see a list
of any parameters that have been added to the project. Clicking the Add
button opens the Parameter Properties dialog box, shown in
Figure 6.21
.
This is the same dialog box as in the Family Editor but with additional
settings to assign the parameter to an object category. The object category
list includes all the component families, system families, in-place families,
andevenmetadatathatmaynotbephysicalgeometry,suchasviews,sheets,
project information, and so on.

Parameter Properties dialog box for a project parameter
The settings for creating a parameter or adding a shared parameter are the
same for project parameters. The only difference is the Categories section of
the dialog box. This is where you can select the Revit category to which the
project parameter you are creating or the shared parameter you are loading
is applied in the project.
