Wish - Extract mesh naked edges

Rhino Rhino for Windows
1

I’m trying to obtain some curves from a mesh model I made, and I’m not sure if the workflow is the best or if there could be a better tool.
Using _Unweld with a suitable angle and then exploding the mesh lets you divide the model in several parts and obtain edges with duplicate border.
I would appreciate having the option to obtain those edges that are highlighted, although this edges ar not dividing a part completely, as in the example.

Then I realized that _DupMeshEdge is almost what I want, the only difference is that you have to choose one by one the angles and not all at the same time.

Hi Joaquin- so the polylines you are interested in are along all the unwelded edges, is that correct, not necessarily naked edges?

Yes Pascal, not necessarily naked edges.

Hi Joaquin- my guess is this is pretty easy, technically ( @tim, am I lying?) . I’ll add the wish for v6, but I don’t make any predictions as to whether or when it will get in.

Thanks a lot Pascal, this could be very useful!

@pascal, RhinoScript’s MeshNakedEdgePoints method might be useful…

Thank Dale, is this something I should understand or I need developer skills?
