Elevation Problem

[tinboye]

I have a drawing with 3 different levels. basically my basement, then you come up the stairs, and there is a little landing to go into the backyard, then there is another set of stairs 18" high(3 steps) then the main floor.

So in the software(latest version)
I have

this is what it looks like:

the dark grey is the section that should be 1'6"
where the white section should be 8' tall.

anyone see why this is rendering this way?

When you get this kind of mixed colors on walls, it generally means that there are some superimposed walls at that place. You should probably try to adjust the height of your walls.
