View Level Association

One thing to remember in Revit is that Plan Views in your model are associated to a level, and they are associated to this level forever. The Views Associated Level Parameter is greyed out and cannot be changed.

This means that if you need to create a new Level or Plan view of your model ensure you are aware of the Associated Level.

It is never a good Idea to copy up level markers to create a new level as the new level will have the associated level of the original copied level.

If you need to create a new level in your model, use the appropriate Level tool located in the Architecture ribbon.

When you are using the Duplicate tool to create additional plan views of your model, ensure you are using the correct original view to begin with. Just because you rename it and adjust the View Range, it still may not have the correct Associated Level.
