Hi David,
Your demonstration was very useful. I am using Chief Architect 10. I can now reproduce what you showed me. However, I do want the great room ceiling planes to run contrawise to the direction of the patio ceiling planes. I tried reversing the "great' room planes, and the room wall/ceiling results are not right. Do you mind building the "great" room ceiling planes contrawise, and showing me how to fix the room wall heights (default 120") and ceilings?
Thanks,
Bob
