Pick CurtainGrid Lines from a linked Curtain Wall?

I’m trying to get the Curtain Grids lines from a linked Curtain Wall. I started with the selection node from Springs, but all the stuff on top of it makes it really hard to tab into if ever. I tried a drag selection and filter but the project manager says he’s still got to unpick on the ones he didn’t want in the drag, so then I tried putting them in Data Shapes and they could pick radio buttons, I picked the first 4-6 assuming they’d all be on the same end, but the order feels random. So I’m back to thinking surely there’s an easier way to just pick the grid lines from a linked wall?

found it, I can’t sort the Data Shapes or it rearranges them.

Hi @TurtleWolfe ,

What does your Dynamo script look like? Seems like you have some good ideas about multiple approaches but are just missing some small steps to make them work.
