Rules for Opening CATIA V5 Models with an Associated Design Table from the Workspace or from CATIA V5
Consider these rules:
When you open a generic CATIA V5 CAD document from the workspace, it opens the model in CATIA V5.
* 
If you want to view or modify the design table, you must do it from CATIA V5.
If an instance CAD document is not in the workspace, the system attributes created by the Windchill Workgroup Manager may not be up to date.
If you select a generic CATIA V5 CAD document to open and the generic is not in the workspace, the generic and all instances are added to the workspace.
If you select an instance, and the instance is not in the workspace, then the instance and its generic CAD document must be added to the workspace.
