In the following sections, we will discuss how to create both of these parameter types as well
as the pros and cons of each.

Creating project parameters
You can create custom project parameters at any time in the project cycle. Depending on how
you create the parameters, you can assign them to one or more element categories within the
model. You can also assign them to elements that have already been created or to element
categories for elements that you have yet to create.
The following steps will allow you to make a custom parameter that can be scheduled but
not tagged. For this example, pretend you are working on an existing building and reworking
a space. Much of what is onsite will need to be demolished, but you would like to reuse all
the elements that are salvageable. As you are documenting the existing conditions, you want
to schedule the elements you want to keep. To do this, you’ll make a parameter called Reuse.
Continue with the project file from the previous exercise (c18-Dimensions-Start.rvt or
c18-Dimensions-Metric-Start.rvt).
To add a new project parameter, follow these steps:
1. Go to the Manage tab in the ribbon and click the Project Parameters button.
This will display the Project Parameters dialog box (Figure 18.44).

dialog box

2. Click the Add button to open the Parameter Properties dialog box. Here you will be
asked to define a list of properties for the new parameter.

Let’s step through what these selections will be (Figure 18.45 shows a view of the com-
pleted dialog box).
3. Set the Parameter Type to Project Parameter.
