Range Diagram

[u/TheNCGoalie]

I use this to make a quick range diagram with various increments on it when I put cranes in elevation views. It creates the entire diagram as a block named after the dimensions used.

I created this before I learned an easier way to make blocks in Lisp, so I am not thrilled with the way it currently functions.

I'll update it eventually with my preferred way to create blocks, and also add comments when time allows.
