I think I know the answer to this but why not ask.
I have a host revit file with two instances of a linked rvt model therein of levels 5 and up where the tower is a miroor of itself - all three models each share commonly named levels.
Now in the host file, I have created a door schedule for the doors within the host file and the linked tower. My issue is that I do not seem to be able to apply a filter "by level" to the doors within the linked file. Should I be able to?
My suspicision is that although my levels are exactly the same, somehow my survey point in the y direction is off bit a tiny smidge and thus Revit does not "read' the shared levels. - do you think this could be true?
All help would be appreciated. On a side note, I also truly wish you could toggle on and off design options in a linked model so I could create two design options for the two varied base tower conditions. brilliant ideas welcome.
