Create lines between points that are perpendicular

Hello people,

I’m new to dynamo and try to auto dim a floor. Now I have points that are perpendicular to each other but I can’t create a line between them (I guess with Line.ByStartEndPoint). The filtering is the problem… I just can’t figure it out.

Any tips about workflow are welcome!:slight_smile:

Thanks in advance and enjoy your workday.
