1. Pick the name you want the Views and Level to use. ie: Level 1
2. Rename both the Floor Plan and Ceiling Plan something different (not Level 1) and nothing already in use. This is a temporary name.
3. Rename the Level to be Level 1
4. Rename the Floor Plan and Ceiling Plan Level 1
5. Now try renaming either the Floor Plan, Ceiling Plan or Level and you will get the ‘renaming’ message again and you can say ‘Yes’
