Hmmm. I first set the pitches in both high wall specifications. Then I used the build roof dialog to create the roof but the pitches were changed to the default of 8". Changing the high wall pitches individually changes nothing.
Is it possible to create this roof using Home Designer Architectural v 19.3.0? The drawing shows the rooflines in red as a rectangle bisected into two right triangle segments by the ridge.
The pitches are indicated by black arrows. The image below gives one perspective of a similar roof. Thank you.
