I built a logic of maximizing south facade area as one of my multi objectives and got some problem when I tried to make polylines as planars(option#1 in the file). Therefore, I used 4point surfaces command(option#2 in the file) and it worked. I don't know why the polylines -planars logic didn't work out.
I uploaded my files.. If you guys have some time, please look at it and give me some clue for this issue.
