Ok i feel like there is a simple solution to this, but i can't seem to find it.
All i want is to import a model and procedurally select one edge from it. Not edge loop, just one edge ... and it doesn't matter which one. Then create a group out of it.

Tried just putting "p0-1" into a group, but for some models, the points are not next to each other, so it's not working. And i don't want to use the sort node and mess up the order of the points, because it may cause problems for my workflow ...

you can do 0e0which is the syntax for <prim>e<edge> so 0e0would select first edge of first prim

Works, thanks!
