In-Depth Information
Project parameters
exist only in the project environment, as the name
suggests. They can appear in schedules but not in tags. Their main
advantage is that you can apply them to all families of a particular category
or even multiple categories in a project instead of having to add the same
parameter to every family. Project parameters can be created from the
Project Parameters tool under the Manage tab.
Choosing the Correct Parameter
The first decision to make is what type of parameter to create. Family
parameters can be created when working in the Family Editor, and they will
be visible in a project when the family is selected. However, the information
that they hold cannot be used in schedules or reported by a tag or
annotation. Shared parameters can be used the same way that family
parameters are used, but they are unique in that they can also be used
in schedules and tags. However, this rule has its exceptions. For example,
in a detail component family, you can't create shared parameters; you can
create only family parameters. But family parameters created in a detail
component family can appear in schedules yet still not in tags. Parameter
types are discussed in further detail later in this chapter.
Naming Parameters
When you choose to add a parameter, it is likely that you have a specific

to consider when you decide what to name the parameter. There is no harm
innaming yourparameters inadescriptive manner, especiallywhenyouare
working with others who need to understand the purpose of a parameter.
However, it is possible to be too verbose. Long parameter names can cause
the annoyance of having to resize columns within dialog boxes in order to
read the name.
Consistency is the key to good parameter naming. It can be frustrating
to go from one family to another and see different names for parameters
that provide the same information. Using descriptive words is also helpful,
especially when you have similar parameters within the same object, such
as a component that is made up of multiple shapes, each requiring a Width
