To be able to display a workset from a linked model in a host view, the workset must be open when you load the linked model into the host model. 
- In the Project Browser for the host model, under Revit Links, right-click the name of the linked model, and click Manage Worksets. 
  This option is only available if the linked model is loaded and workshared. 
   
- In the Manage Worksets for Link <filename> dialog, select a workset, and click Open. 
- Click Reload to reload the linked model and open the specified worksets.
