Show Choir Risers

This is used to visualize a show choir stage. Developing staging is fun and hopefully, this will let you mix and match the standard US riser sizes of 8 feet X 4 feet and one each of 8, 16, 24 and 32" high. They are using 1mm = 1inch scaling,

I'll be doing other pieces/parts with the same scaling including riser wedges, steps, performers, and lighting fixtures.
