P.S. By the way, I found three things while messing about, all shown here:

  1. A simpler way to get the BBX and SrfSplit.

  2. Boundary surfaces overwhelm tower surface color. This is an unfortunate relic that’s difficult to explain - when rendering colors, upstream geometry takes precedence over downstream geometry with regard to transparency, so in this case I made the tower surface color opaque.

  3. The Offset Surface at the lower right is working now but because surface normals changed, it needs a negative ‘D’ value. I didn’t touch it.
