I am not running 8.0 anymore, but 9.0 and 9.1. The Family Type is located under the Settings menu, but is grayed out until you are in the Family Editor, editing a component or standard family (RFA) file. The Family Type (see Help)command can also be access:
In the Family Editor, create the family component and label the permanent dimensions that appear. See Family Editor.
On the Settings menu, click Family Types, or click Family Types from the Design Bar.
Time to update your Revit, YA Think!
