The next step is to create a new layer for adding the room names.
As with previous steps where new layers were added, the same process must be followed to create a layer for the Room Names.
First, open the sidebar.
Second, lock the Dimensions layer since no additional changes will need to be made.
Fourth, as before, double click on the newly created layer (Layer 10) to rename it to Room Names.
Lastly, make certain the Room Names layer is selected and then dismiss the Layers Panel by clicking outside of it.
The Layers Panel should appear as shown below once these steps have been completed.
