I need a Wall family that has a Heavy (dark) line on the outside and a Thin (light) line on the inside. The intent is to de-emphasize the stud line for these wall types that are used to, say, enclose columns.
I've moved the "Core Boundary" to either side of the Finish 1[4], and have only a Structure [1] towards the inside.
How do I get the Structure to be a thin line for this wall type?
