OOTB, I am not sure how to do that. But using springnodes, we can add an additional output to his node.

Paste the following python script into a fresh Python node.

@john_pierson Perfect.

How can I return the edge as Edge and no as Curve?

Change this from
edge.AsCurve().ToProtoType()

to
edge.ToDSType()

k, do this instead.

Change this from
edge.AsCurve().ToProtoType()

to
edge

beyond that, open a new topic and try to explain what you are wanting to do with edges.

Hello guys, while I was searching how to solve this problem I found this solution. It’s exactly what I’m searching for except that with multi-edges from different families it gives me only one family in the output.
So how can we get the family of every edge selected?
