Dynamo to return Multiple Intersections between Multiple Elements

Revit

1

Hello all, I am looking for some assistance with my dynamo file. I am trying to find the intersections between multiple extruded curves & multiple selected faces. I cannot for the life of me figure out why I can’t get the list to return values. If I select only the single face I can get it to work…I have linked the video I started from as well as my files. Any help would be great!

Make sure your inputs are flattened and the intersect node is set to Cross-Product lacing.

Nick,

Thanks for the reply! It was the lacing!
