<t>Some of my walls are not showing the correct color in 3D view. I have the north wall showing a nice pale yellow.The pale yellow color looks gray on the other walls even though the code number is exactly the same as the north wall. Even the little color icon in the modify box shows the right color ...

how do I add a wall opening for doorways with no doors? I tried door frame but the opening does not go all the way to the ceiling like some of mine do in my home.
