Assets are automatically displayed using the "_Facilities Workmodel" reference Design Model and all levels are turned on. What happens if I remove the "_Facilities Workmodel" Model or the attachment to that Model? Also, is "_Facilities Workmodel" the name used when the master model is 3D and "_Facilities Workmodel_2D" the name for a 2D master?
The "_Facilities Workmodel" Design Model is used to manage dynamic Assets. If you remove or detach the Model, the next time it is needed it should automatically be recreated and/or reattached. And yes, the "2D" suffix is used when the master model is 2D instead of 3D.
