Geometry.DistanceTo List Management Issue

[David3]

I’m having a hard time wrapping my head around how to correctly use list management to achieve what I’m after. I would like to determine the distance between surfaces. Ideally comparing only items within each sub-list. Is there any easier way to go about this? I feel like I’m close.

Thanks in advance!

Can you upload your dyn and rvt files so people who want to help don’t have to spend time rebuilding everything to get to where you are? That part of the process is very time consuming.

Not sure of what your end goal is, but see if the “List.EveryOther” node from springs helps:
