• Non-file-based attribute—Windchill attribute that is not visible or modifiable in the authoring application. Although its value can be added, modified, or deleted through Windchill, it is not passed to the CATIA V5 model file, and, therefore, is not accessible in CATIA V5. You can edit non-file-based attributes on family members only in Windchill.

• File-based attribute— Windchill attribute that you can edit only from CATIA V5 (you cannot edit configuration specific properties using the Windchill workspace Edit Attributescommand).
