Find closed curves from holed surface

[2shy]

Hey, I’am trying to create automaticly area plans for flats but I’am stuck on generating closed curves for AreaSeparator.FromCurve node. Some of found surfaces that I was planned to extract preimeter curves from appeard to have holes inside. Thats why I cant make closed curves, no idea how to choose both hole and preimeter curves from surface separetly.
Thanks in advance.

There’s an old Archi-lab node, Group Curves, that will group curves in closed loops. Not sure if it’s still out there but that will do what you need.
