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 Menu.
Second, lock the Kitchen layer since no additional changes will be made.
Third, press on the Add Layer Button to create a new layer.
Fourth, as before, press on the Edit Button and rename Layer 9 to Dimensions.
Lastly, make certain the Dimensions layer is selected and then dismiss the Layers Menu by tapping outside of it.
