I have created a graph for calculation of roof element perimeter. The graph works fine but not perfect. Now when I look at it I can tell which one is the perimeter based on the two biggest numbers. However, I am looking for more straight forward (one number) solution. Do you have any ideas how to do this? I idea was to extract the bottom surface of the element, get the perimeter lines and sum their lenght. Idk if such an aproach is good and possible at all. Thanks.
