Toposurface shades ramp

[ricardo.o.maciel]

I am using toposurfaces for driveways as splitted graded surfaces. To obtain the cut/fill schedule, parts of the same surfaces cross underneath ramps, floors and walls.

Everything works fine in 3D. In floor plan views, however, parts of ramps seating close (but above) surfaces are shaded by them.

Is there an explanation for this behavior, and means to avoid it?
Attached is an example of this scenario.

Ricardo, that's an issue I ran across last January too. I filed a Support Request and the last I heard from Support was on February 7th. The issue was supposedly sent to development. There should be no reason it acts that way. In the meantime your only solution is to use a masking region to hide the buggy result.

Thanks, Dave.
As usual, you saved me a lot of time.
