The easiest way is to download [uto]'s Mesh Analysis Utilities from here: http://www.grasshopper3d.com/profiles/blogs/mesh-analysis-and-utility

and use the Naked Mesh Edge component.

I think I'm going crazy, or this forum is buggy (probably the former).

This message was posted like 5 hours ago but I just checked the thread replies 3 minutes ago before replying myself and I can swear all were about Convex Hull.

Hi Ognek,

 

have you tried the Convex Hull component next to Delaunay? It should give you those points.

If it doesn't what am I doing wrong?

Try getting the naked vertices of the resulting mesh.

 

Kangaroo has a component for this. If you don't have it installed, just connect the mesh to the x input of a VB component and insert this code:

  a = x.GetNakedEdgePointStatus

 

It will output a list of boolean values you can use together with a cull component to filter out the vertices in the border.
