dodger

well this almost works, only now i cannot get grass into center, it just shows white, like it is nothing there.

i am trying to figure out how to create a donut shaped house, where there is a hole in the center that is actually outside garden. and the living quarters are the donut. how do i "cut through" so that exterior walls are in inside of first ring? sory if this is hard to follow, i just do not know how to explain what i am trying to envision.
