Geometry.intersect with paired items in 2 lists

Hi guys,

I am looking for any solution for this intersection geometry check with paired items in 2 list. Please see attached image and you could understand my matter.

Thank you very much for your help !

If you upgrade your dynamo version to 1.2 you’ll be able to enable the list at level feature1, which in turn allows you to set the geometry input to be @ level 2, and leave the lacing set to cross product. That should get the desired results.
Otherwise you’ll need to turn to a list map node, which is a good bit more difficult than the list at level feature.
