Schedules and Parameters
Because of the relationship between objects, parameters, and
schedules, the data within a Revit schedule is the same as the data
assigned to the objects. This is known in Revit terms as bidirectional
associativity . It is best to have a good understanding of how
parameters work when you set out to build a schedule. For more
information on the creation and management of parameters, see
Chapter 6, “Parameters.”
To establish the columns in your schedule, you simply select the parameter
fromtheAvailableFieldslistandclicktheAddbuttonatthetopcenterofthe
dialog box. This places the chosen parameter in the space on the right side
of the dialog box. Another way is to double-click the parameter you want to
add. Each parameter added to the schedule will be a new column, and the
order in which they appear in the list determines the order of the columns
in the schedule, from left to right. Once you have added a parameter to the
schedule,youcanusetheMoveUpandMoveDownbuttonstosettheorder.
These buttons become active only when you select a parameter from the
Scheduled Fields list on the right.
The Remove button at the top center allows you to remove a parameter
from the schedule. This is not the same thing as deleting a parameter.

project and any objects in your project.
If you want to schedule information about the chosen category and a
parameter does not exist that contains that information, you can click the
Add Parameter button at the center of the dialog box. Clicking this button
activates the Parameter Properties dialog box, where you can choose the
type of parameter and its properties. The check box in the lower-left corner
of the Parameter Properties dialog box (Labelled “Add to all elements in
the category”) is selected by default, and it is grayed out to ensure that the
parameter you create is added to all the objects in the category you are
scheduling. Once you have created a parameter, it is automatically added to
the schedule.
