List of lines/curves to make a quadrilateral or polygon

Hi,
Im trying to make this green colored lines as a closed loop polygon/ curve to check whether the list of objects are within it or outside. But Im not able to make closed loop :pensive:

**

Next step is from this closed loops polygons I will check the list of objects are within the boundary or outside of it. Probably I will do it with bounding box

Anyone got idea how to make closed loop curve or red-list to to be identified within the curves. :thinking:
Your comments on it would help me alot.

Did you try PolyCurve.ByCurve / PolyCurve.ByPoints?

At least one of the rooms has more than 4 lines defining its perimeter so chopping by 4 isn’t going to work here.

Try using a GroupCurves node from Archilab, and build your polygon from that.
