Hi guys. I’m trying to solve this problem but can’t think of a suitable solution. I need to select lines that intersect other lines at 2 points like the red lines in the image. the amount of work is quite large so I thought if I could ask someone to help me write a python script for it. Thanks

grasshopper will do the work. Is this helping?
I don’t konw if it’s the best solution.
