I have a thirdf floor view that continues to show the 2nd floor room fill colors, despite the fact that underlay is off. Floor 3 is visible and present (though) I can't grab it because I don't cotnrol that work set. The third floor room fill is not visible unless I make the cut plane 10'. That suggests that the 3rd floor is out of place, I think. But it seems fine in section.
I can't figure out if this is a bug in the view range or a problem in the model.
Note that the upper range is 12'2"
The bottom of the range is offset 4' to show a parapet/roof of an adjoining structure.
The clip depth is not effecting the visibility of the 2nd floor room fills at all, though it does effect the 3rd objects like the parapet.
I would think the clip depth would get rid of a lower floors room fill, which I assume is associated with the floor object.
Can you post your file and some images?
If you go to a section cutting one of those rooms and check the room itself, can you confirm that the rooms are going from the bottom of the floors to the ceilings?
Glad to hear you got it working!
