Pipe Crossing top and bottom elevation

I am trying to figure out how to get the elevation at the top of the bottom pipe and the bottom of the top pipe in a plan view label. I started with the script here CivilEnvoy: Civil3D : Dynamo Script for Pipe Crossings

I would appreciate any help, and since I am floundering here even just pointing me in the direction of where to start learning some Dynamo this would be greatly appreciated.

Hi @White127,

See if this helps.

Thanks,
That’s the file I started with and am trying to build on. It’s getting the clearance between the pipes and that distance so I know it has the info I need in there somewhere, I just can’t figure out how to get it.
