Help in intersection between two different lists

Hi folks,
I am really new in using dynamo, so I hope you can help me ,

I have two lists, List A contains lines ( represented by points ) . list B is some random points. the two lists don’t have the same number of items, I need to know every point in list B intersection with list A and represent that in one list.

Thanks in advance :slight_smile:

You can use Geometry.DoesIntersect, you get a list of Booleans (true/false) that you can use to filter your point list with List.FilterByBoolMask.

Something like this ? Note the cross-product lacing on Geometry.Intersect
