This dialog box is the first place to go when adding a parameter to a family,
a project, or a schedule.

There are four basic kinds of parameters in Revit MEP: system parameters,
family parameters, project parameters, and shared parameters. Some
parameters are hard-coded into the software. The values of these
parameters can be edited as needed, but the parameters themselves cannot
be removed or modified. In this chapter, these are referred to as
system
parameters
.
Family parameters
are used to build and define graphical structure and
engineering data within component families. These parameters can be
customized as needed to enhance the capabilities of component objects and
to extract and analyze data.
Shared parameters
are useful to help maintain consistency within families
and to coordinate information within a project. They are the most useful
kind of parameter because they can be used in component families,
schedules, tags, and annotations to report the same data in whichever
format the user chooses.
