Extract continuous curve from mesh

Hi all,
I wonder what’s the quickest way to extract one of the edge curves as a continuous line of a closed mesh?
Thanks for your help in andvance!

(I played around with: extract wireframe, select chain, rebuild, etc…)

Cheers, K.

Hi Klaus - is it along a naked edge of a mesh, a crease, or some interior edges?


Hi Pascal,

THX for your response.
It’s a sharp edge of a mesh.

Kind regards K.

Hi Klaus - DupMeshEdge may be the thing then.
