I have created the roof the way I want it to be displayed, but when I go to add new walls or adjust ceiling heights in my rooms, it changes the way the roof is created! How can I stop the roof from updating every time I go to make a change?
To stop the roof from rebuilding, you need to turn off the Auto Rebuild Roofs feature.
To turn off Auto Rebuild Roofs
First, launch your Home Designer program and Open the plan which has your roof created as desired.
Select Build> Roof> Build Roof to display the Build Roof dialog.
Uncheck Auto Rebuild Roofs and click OK.
Now that you have unchecked this option, the program will no longer automatically rebuild the roof if you make a change that affects the generation of roofs, such as to exterior wall positions or room ceiling heights.
