The next step is to create a new layer for adding the dimension lines.
As with previous steps where new layers were added, the same process must be followed to create a layer for the Dimensions.
First, open the Layers Panel.
Second, lock the Kitchen layer since no additional changes will 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 newly created layer (Layer 8) and rename it to Dimensions.
Lastly, make certain the Dimensions layer is selected and then dismiss the Layers Panel by pressing on the Hide Sidebar Button located in the bottom left of the panel.
The Layers Panel will appear as shown below once the above steps have been completed.
