ANSWER
A reverse gable, sometimes called an opposing gable, is perpendicular to the main gable roof. A reverse gable can join the main roof anywhere along the main roof. In this example, it joins the main roof at one end.
To build an automatic L-shaped reverse gable roof
- First, launch Home Designer and choose to start a New Plan
.
- Next, select Build> Wall> Straight Exterior Wall
, and draw the walls for your L-shaped structure in a clockwise fashion.
- Using the Select Objects
tool, select the wall, then click and drag its end out to extend the wall through the bump-out of the L, so we know precisely where to place our wall break.

- Select Build> Wall> Break Wall
from the menu. Click to place a break in the wall where the wall extension meets the gable.
