Multiple Naked Vertices Fix?

Hi,

Is there a way to automatically find and delete/collapse multiple faces with naked vertices? I have a lot. Mesh is welded. Also tried wbJoin

Thanks

Can you post your definition and rhino file?

Hi David,

Didn't use GH to create this. The mesh was imported (Maya nCloth to ZBrush then Rhino) and is over 100MB. I'm avoiding using the CollapseMeshFacesByArea command because I don't want to collapse faces that may not be an issue. I was looking for different tools to cull those naked verts and all I found was the script below, which I tried but it didn't do anything on my system. Been deleting them manually.

can't you sort them by area and delete the smaller one with a tolerance reference value ?

edit : weavebird includes a naked boundary component

here...I think this is what you're trying to do? You'll need kangaroo for the naked/clothed vertices and to get the vertex neighbors. What you do is identify all naked vertices and isolate the indices of those that are only attached to two other vertices (so they're "hanging" freely, as if the opposite edge is a hinge). Then you use the "member index" component to compare the vertices from each of your faces to the hanging vertices, collect any face that hits the mark, merge them and use that list to "delete faces" on your mesh.

Can you please show that definition using the text display? I have Kangaroo 0.085 installed but I'm not seeing the icons in your definition. Thanks, I really appreciate the help.

No worries...although I'm not sure if if your version will have all of these components...

looks like I'm missing the first two components: NakedVertices and VertexNeighbours. Are those both Kangaroo components and do you think I should download an earlier version?

Yes those are both kangaroo...yeah, I would download an earlier version.
