Hello,

I have two lines and I'm trying to use “intersect” in a wrangle node to select primitives on one curve based on the @N direction on the other. But I can't figure out how to do that. I have a hunch that getattrib or pointattribute might be the way to go but I don't know how to write it properly and couldn't find any examples.

Hey BabaJ!

Yes exactly like that, but when I try it for the scenario I actually want to use it for it doesn't work, then it selects the source points

(You possible have to plug in the OSM file into the first node.)
