Geometry.Intersect - Empty List

Hi, I’m having trouble with Geometry.Intersect. I’ve taken a screenshot below. I’ve also tried using other intersect operations and all give the same empty list result. there are a couple of intersecting points that do appear but the majority don’t come up/come up as empty list. The Scale is set to Extra Large also.

Can someone please advise me on how to move forward? or provide another method of identifying pipe penetration through floors (floors via linked model).

Appreciated!

Hello and welcome ;)…first it seems you had problem with node “element getfromfile” try to open the node and edit the input node…probably you still will get an empty list then try list clean or just a list flatten
