Thanks, Eduardo:
I have checked those settings, and how they relate to 2D display on each floor, but it hasn't quite worked out, unless I'm missing something.
Let me describe what I'm trying to accomplish:
On the Stair's Home Story, I'd like the Visible treads (below the break line) to be pen #5. An then on the Story Above the home story, I'd like the Visible treads (ABOVE the break line) to show in pen #6.
Does that make sense?
