Here is the layout ISOified. Torstan's one-sentence explanation about how he did it for his Bandit Layer map helped a lot in figuring out how to go about it. He said, "The workflow was to create the top down plan of the dungeon. I then rotated each layer by 45 degrees and shrank the (new) vertical axis to 57.7% of it's original value. That made it the correct dimensions for an iso grid." You can vaguely see I have that written in white text at the bottom there. I always write little notes to myself on my maps to help me remember what the heck I am doing.
