Project parameters are a great way to use shared parameters in families
without having to edit each family individually. The check box in the
lower-left corner indicates that the parameter will be added to all elements
intheprojectthatbelongtotheselectedcategory.So,ifthereareparameters
that you want to use on a particular category of elements, such as light
fixtures, you can create the parameters as shared parameters and then load
them as project parameters into your project template file. Then, whenever
you load a family belonging to that category into your project, it will have
the desired parameters, which can be used for scheduling or tagging.
Additionally in this dialog box are the radio buttons Values Are Aligned
Per Group Type and Values Can Vary By Group Instance. They appear
uneditable when Type Of Parameter is set to the default Length, but if you
change it to Text, Area, Volume, Currency, or a few more, you will be able to
switch between the two.
Values Are Aligned Per Group Type (Default)
If an element with
this instance parameter is part of multiple groups, the parameter value
will be the same for corresponding elements in all group instances.
While in Edit Group mode, you can select the element and modify the
parameter on the Properties palette. Changing the parameter value for
the element in one group will change the value for the corresponding
element in all other instances of the same group type.
Values Can Vary By Group Instance
If the element with this
instance parameter is part of multiple groups, the parameter value can
vary for corresponding elements in group instances. While in Edit
Group mode, you can select the element and modify the parameter on
the Properties palette. Changing the parameter value for the element in
one group will not change the value for the corresponding element in
other instances of the same group type.
If you change an existing parameter from Varies to Aligned, an error
message appears, listing the elements with the parameter that will change.
If you click Align Parameter Values, then all group instances will update
to have the same parameter value. The value applied is the value that was
assigned to the element in the first group instance.
