Trying to build a wall 1.5' high and then a separate wall 7.5' high on top of that.


On the "Plane" view, I can change the wall parameters to partial, and set the height. On the "3D" view, I can see that it correctly drew the wall.


But when I try to draw another wall on top of it, it just "snaps off" and disappears.


What am I doing wrong? Is there no way to draw a wall on top of a wall?


Alternately, is there another way to have a wall that has 2 different textures on it, and 2 windows (one on the bottom, one on top, different types)?
