I'm having trouble with common wall edge lines being drawn/printed over the outer wall cut line in plan view. I would like the common wall lines to be gray, but when I do so, these lines print over the outermost cut line.

Yes, this would be imperceptible with a physical print. However, I very much would like the PDF to render as shown in the Revit screenshot. Any hints would be much appreciated.
