Rules for Opening a Part Family (NX)
Consider these rules for using Open or Open from Windchill:
• You can open each member of the part family individually if it is managed in Windchill.
• If you select a top-level generic to open and the generic is not in the workspace, then Windchill Workgroup Manager adds only the generic to the workspace.
• If you select an instance, and the instance is not in the workspace, then the instance and its Part Family generic must be added to the workspace.
