When I select Build> Roof> Build Roof from the menu and click OK in the dialog, no roof is created. Why is that happening and how do I fix it?
There are several reasons why a roof might not be produced in a given plan. We will discuss the most common reasons why a roof would not be generated below including room definition, structural specifications and Roof Baseline Polylines.
Home Designer Architectural and Home Designer Pro have a Gable/Roof Line tool which can be used to automatically generate a gable above the bearing wall of a hip roof plane such as if a Wall Break would be required in the same location as a door or window, where a wall is not present, such as across the front of an alcove, or over a Bay, Box, or Bow Window.
If you have tried to use a Gable/Roof Line in a different area than those described above, it may be undesirable affecting the generation of the roof planes. Using the Select Objects tool, you can select the Gable/Roof Line then Delete it.
If another object in the area select first, then use the Next edit tool, or the Tab shortcut key on your keyboard, until the Gable/Roof Line object is selected, then remove it.
In Home Designer Pro, an unwanted Roof Baseline Polyline may prevent the roof from generating properly.
You can quickly remove any Roof Baseline Polylines from the current plan by selecting Edit> Delete Objects from the menu.
In the Delete Objects dialog, select All Floors, check the box beside Roof Baseline Polylines, click the Delete button, and then click OK. Lastly, rebuild your roof.
If you have set one or more rooms to be in a Roof Group other than zero, you can use the Reset to Defaults menu option to set them all back to zero.
Select Edit> Reset to Defaults to bring up the Reset to Defaults dialog box.
Place a checkmark in the Roof Groups box and then click on the OK button to reset all the rooms to Roof Group zero.
Then select Build> Roof> Build Roof from the menu, place a checkmark in the Build Roof Planes box, and click OK in the dialog
