How do I create an 'L' shaped structure with three full gable ends automatically?


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

  1. First, launch Home Designer and choose to start a New Plan .

  2. Next, select Build> Wall> Straight Exterior Wall , and draw the walls for your L-shaped structure in a clockwise fashion.


  3. 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 known precisely where to place our wall break.

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

  5. Once the break has been placed, use the Select Objects  tool to select one of the walls indicated below in red.

  6. Once selected, click on the Open Object  edit tool to display the Wall Specification dialog.

  7. On the Roof panel, place a check mark next to Full Gable Wall, then click OK.

  8. Repeat this process for each of the wall's indicated in red in the image above.

  9. Pull the wall's end back to its original location.

  10. Select Build> Roof> Build Roof  from the menu to open the Build Roof dialog.

  11. Set your roof's Pitch and click OK to build the Roof.

    In Home Designer Pro, you need to check the Build Roof Planes checkbox before clicking OK to generate the roof planes.

  12. Select 3D> Create Camera View> Full Overview  from the menu to see the results.
