How to fix plans and elevations set up in a host file when a linked file is moved in the host file:

If a building you have linked into another Revit file via shared coordinates is moved (because it was located properly related to another building for example), all of the views associated with that building that were created in the file the link is hosted in will have to be adjusted.  These views are the ones you are putting on sheets in the host file.

It's a tedious process, but not really that bad.  All you have to do is adjust the crop region (for enlarged plans for example) and move it the same distance in both directions as the building moved in plan.

This will also apply to elevations you have created in the "Host" file.  They will have to be moved as well, of the "viewport"/crop region will cut off part of the elevations.

In my case, the building moved 1'-4" in the x-direction and 6.5" in the y-direction.  I just went into each of my enlarged plans related to that building and shifted the crop region and any elevation tags the same distance in both directions and all my views showed correctly again.
