I am trying to extract naked vertices from a mesh that I created from originally two cuboids. Here’s what I did. I made two cuboids inside Rhino I did Boolean union of them. I exploded the result. I removed topmost and bottommost faces. Inside Rhino, I joined all those faces, then created one sin…

[image] archz2: Here’s what I did. I made two cuboids inside Rhino I did Boolean union of them. I exploded the result. I removed topmost and bottommost faces. Inside Rhino, I joined all those faces, then created one single BREP out of them. I converted that BREP into a mesh. Then I inserted th…

You need to weld the vertices. As @HS_Kim shows you could use combine and clean which does a welding as well. You could also use the join + weld from Weaverbird, weld mesh from Mesh Edit, or rebuild mesh from Pufferfish. Since Kangaroo now comes with Rhino 6 + Gh 1 natively, combine and clean will …

[image] Joseph_Oster: Having gone that far, why not just convert the two faces you removed to meshes and get their “Naked Points”? That’s because those naked points have to be the part of the final mesh. The two faces I removed will be separate from the resultant mesh.

Okay, so now I understood the ‘how’ of the process, I am trying to understand the ‘why’ to form the foundation of my understanding. [image] Michael_Pryor: You need to weld the vertices. So what I can figure out, the naked vertices were initially being given for every flat face despite the me…

Not really, it means you have verts which are duplicate where brep faces meet and we need to weld them into one. Very common mesh thing.

[image] Joseph_Oster: This can be done without NakedVertices Yeah. That’s slightly similar to what I was talking about in my original post. [image] archz2: Of course, I can create more BREPS at the outer vertical edges for selection, then use point in BREPS, then dispatch, then cull(remo…

There are some other mesh weld features including vanilla GH Weld Mesh. [Canvas%20at%2002%3B46%3B46]

[image] Michael_Pryor: Not really, it means you have verts which are duplicate where brep faces meet and we need to weld them into one. Very common mesh thing. That’s what I’m wondering about. I mean the need of the resultant mesh preserving the duplicate data instead of combining it into one…
