I’m trying to create a .dyn which will override the color of a ceiling based on it’s height offset from level. I’m able to get this to work nicely, but the order in which the color is applied seems to be based on the element id ceiling element. So…I would like to sort the list of ceiling elements based on their heights in ascending order. That is where I am stuck. I’ve tried using sort.bykeylist without success, because I’m uncertain as to how it works. Thank you for your help.
