I have a void in the top level of a new design (will post some images when complete in next week or so) but the topo that is below the lower level is showing through.
I have checked all the visibility settings that I can think of. What should be showing of course is the level below. How can the topo be showing through the level below when there is a ground floor slab? The level below does not have this problem and shows its floor so it isnt the topos surface protruding beyond the ground slab.
Any suggestions?
