Step 12 - Adding the Doors Layer
The next step in this process is to create a new layer for the Doors.
As with the previous step where a new layer was added, the same process must be followed to create a layer for the Doors.
Second, lock the Door Cutouts layer since additional changes will not have to be made.
Third, press on the Layers Settings Menu and select the Add Layer option to create a new layer.
Fourth, as before, triple tap on the new layer (Layer 4) in the Layers Panel and rename it to Doors.
Lastly, make certain that the Doors layer is selected and then dismiss the Layers Panel by pressing on the Hide Sidebar Button at the bottom left corner of the panel.
