Step 12 - Adding the Doors Layer
The next step is to create a new layer where the door locations are "cut out".
As with the previous step where a new layer for the Interior Walls was added, the same process must be followed to create a layer for the Doors.
Second, click on the Layers Settings Menu and select theAdd Layer option to create a new layer.
Third, as before, double click on the new layer (Layer 4) and rename it to Doors.
Lastly, make certain the Doors layer is selected (highlighted in blue or gray) and then dismiss the Layers Panel by clicking outside of it.
