First, I have scoured the help section, so please don't reply with just "look in the help".
IN the help references, I see screenshots of of 3d views where all elements and walls have black lines at the edges. (see "black_lines.png" below and attached).
However, I can't for the life of me find out how to turn that on! My 3d views are a bit muddy and undefined and walls blend together. Having the black edges would be very helpful (see "no_black_lines.png" also below and attached.)
Any input appreciated, Thanks,
No Black Edges
