ExtractMeshEdge -unwelded API

[Jbok_L]

In Rhino GUI, I can use ExtractMeshEdge to get the unwelded edges of mesh. I’m wondering how can I do it with Rhinocommon API?

I only found mesh.GetNakedEdges() which is the same as ExtractMeshEdge with Naked edge.

Or any other API that can get the outer polyline will help, thanks.

outer polyline

Maybe this can help (provited that the Mesh is valid and manifold):

Mesh naked boundary - any method to make faster and accurate?

I’m trying to get the naked boundary (closed polyline) from two meshes with multiple open faces… I’m getting satisfactory results within geometry, but as I increase the mesh resolution, the time processing rises a lot. Computing with more straightforward methods or some plugin components is much faster. Still, it doesn’t get the completely accurate naked boundary polyline, or they don’t appear in the same topology for later processes like lofting them. (The following steps to consider…I’m doin…

That said a naked edge is one that has one adjacent Face (see RC for stuff related with Mesh Connectivity (Vertices, Edges and Faces)). Note that if an edge has both ends (Vertices) naked … then may (or may not) be naked. Finally keep in mind that the indexing used in the naked Vertices related RC Method is the Mesh Vertices indexing (NOT the Mesh Topology Vertices indexing).
