there is a springnode groupbydistance…

this nodes works pretty good and groups geometry that is close to each other…

i am using it to group walls that are close to each other.

Now i was hoping that it would group it in a fashionable order so if i took the first and the last item that i then have the outer walls… unfortunately this is not the case…

Does some one know how to adjust this python script… so that or the output is in a chronological order… or the output is only the outer geometry of the geometry close to each other.
