I can't get my head around the current system for displaying dwg plans and I am not sure if it is my applied process or a bug.

With a multiple floor, multiple room project, I import a DWG, work on the first floor, complete that floor, then duplicate the elements needed for the next floor (not many elements as each floor is different).

I then import the DWG for the new floor and find that it had applied the view (auto ticked in Displays Plans Tool) to the previous floor AND all the room views. I then went through each room view on the previous floor deselecting the new plan.

I repeat the next floor with the import of a new DWG for that floor and find it has populated the view on the previous 2 floors and every room view!

Am I missing a trick here? Is there a process to avoid this? As you will appreciate this is very time consuming, especially as I have 3 more floors to do.

Any advice is welcome.
