need help with folding on 4 corners

hello,

thanks for this excellent plugin, i have lots of fun working with it. i am beginner to grashopper and kingkong, i managed to work with kongmesh but i have a hard time with the example from a previous post: http://www.grasshopper3d.com/group/kingkong/forum/topics/when-rulin...

i do not understand how to order the folding lines that i can fold 4 folds simultaniously. whatever i tried, i always got errors. so i think i did not understand the underlying mechanism how it works.

if someone could give me some hints, that would be greatly appreciated.

thanks,

michael
