I have an edge group that I made by selected edges on a sphere.

I want to remove everything except the edge.

Blasting non selected with the edge group removes everything but the points. Which makes sense, because there are no line primitives prior to the blast, and the blast removes the polygon faces that were making up the line.

Is there a node to just give me the edge I selected as a line?

The add sop doesn't work because the point order isn't linear and I want to support branching.

Thanks!

It sounds like the PolyCut SOP might do what you're looking for?

Ah, yeah! Thanks! I've never used that before.

In order to get it to work, I had to make an edge group that was *not* my edge, set the type to edges, set strategy to ‘remove’ and untick ‘keep polygons closed’.

It also seems to output doubled up edges, so I had to put down a clean node afterwards to fix overlaps.

Thanks
Ben

This is old topic, but asked frequently, so just wanted to point out SideFX Labs (former Games Tools) has also very clean and easy to use tool for creating curves from edges based on edge group called … well … “Edge Group To Curve”.

Ahaaa! That's great, thanks Beny, just what I was looking for : )
