Wall height in cathedral ceiling room

[Granger968]

Hi there, 

 

Relatively new to Home Designer (Architectural 2020). I have a cathedral ceiling and I'm trying to get the walls in that room to extend all the way to the ceiling. As you can see on the pic, walls 1 and 2 stop at the "standard" ceiling height (9' in this case). These walls will be very flimsy if built as drawn, so I would rather have them go all the way to the ceiling. Wall 3 already reaches the wall, but I don't know why.

 

Any experience with this?

 

Thanks in advance!

Go to the attic level and draw in walls. Set them to Knee Wall to make them not go through the roof.

Thanks!!  I will try this later, but sounds so obvious now that you mention it... 

 

Much appreciated!
