Step 10 - Adding Door Cutouts Layer
The next step in this process is to create a new layer for the Door Cutouts.
As with the previous step where a new layer was added for the Interior Walls, the same process must be followed to create a layer for the Door Cutouts.
Second, lock the Interior Walls layer since no additional changes will need to be made.
Fourth, as before, double click on Layer 3to change the layer name to Door Cutouts.
Lastly, make certain that the Door Cutouts layer is selected (highlighted in blue) and then dismiss the Layers Panel by clicking outside of it.
