I am very new and know this is a simple fix, but I cannot change my wall heights on my plan to anything other than to the top of the deck of the next story. I have tried changing the height in the Wall Preferences, in the Object info pallet and they all stay the same height, extending to the bottom of the deck.
I can see when I draw in 3D that the wall ghosting in at the 3'6" I created it in the wall preferences, but then when it is created it's a full height wall.
