Set name of wall types into intersecting Element(breakthrough)

I created breakthrough families and i would like to fill a Parameter of the wall intersecting breakthrough-family types with the name of the wall type that intersects it. i tried to identify the elements with a node from bimorphNodes(Element.IntersectsElement).

Does anybody has a solution how i can get it? Until now i have sublist of the intersecting walls, but i think because i have more than one breakthrough intersecting the same wall my list is not correctly “mapped” to fill the paramters of the breakthroughs.

Thanks for any help!

I think the solution to the problem may be in this context. Forum is very rich in this subject and you can use .dyn files available.
