Need some help. We have a drawing named "floor plan" xrefed and located in model space of our drawing "sheets" file. The "floor plan" drawing contains its own set of layer states - for floor plan, ceiling plan, etc. I have a sheet setup in the "sheets" file with a "titleblock" xrefed into paperspace and a viewport for the "floor plan" file. When I activate the viewport and run the layer state for the xrefed "floor plan" then the "titleblock" in paperspace turns off. Is there a way to run a layer state in a viewport and not affect paperspace objects?

Unfortunately, I cannot edit the "floor plan" layer states in the "sheets" file because the layer state editor will not allow you to edit layer states of an exerted drawing. Thanks.
