Creating a Roof with a Vertical Penetration from a Footprint
In this exercise, you add a main gable roof to a house from a footprint. The roof requires an opening to
accommodate a chimney.
You begin by sketching the perimeter of the roof in plan view to create the roof footprint. After you define
the roof slope lines and complete the footprint, you sketch a closed rectangular opening around the chimney.
When you complete the roof, the opening that you sketched becomes a void in the roof.
