I was worried at first when I saw all buildings with the same point list numbers but quickly understood why. The squares (and their center points) are sorted by distance to their average, which is a center point for all extrusions in each “clump” (building?). So they all have the same point list, regardless of the random heights. Zero is always the tallest.
So I went back to using their original numbering sequence with a different method. While I was at it, I added the ability to set different height domains. One per building if you like or in this case, just four that are reused.
