Extraction parameter from the list

Hello, everyone
I ve got an list of Rooms.Boundaries defined by 4 lines which of them defined by points, direction and lenght parameters in a string. My goal is to find a minimum X and Y value among those lines among one room. So I am planning to extract only points from this list, but unfortunatly don’t know how to do that. Can someone of you give me advide how to handle this list properly?

Use the Point.X and Point.Y nodes

You need to get the Start & End point of the curves first then sort by Point.?

Unfortunaly it doesn’t work with this node (Clockwork).

Yes, but generally I want to understand how I can handle complicated lists like this, extract any parameter I want.

you need to get a property of the curve before


It was so simple :laughing:
