Hi;
How do I fuse these places?
C++ Repair mesh.3dm (70.6 KB)
CRhinoGetObject go;
go.SetCommandPrompt(L"Select Mesh");
go.GetObjects(1, 1);
if (go.CommandResult() != CRhinoCommand::success)
{
return CRhinoCommand::cancel;
}
ON_Mesh* mesh = const_cast<ON_Mesh*>(go.Object(0).Mesh());
mesh->CombineIdenticalVertices(true, true);
mesh->CullUnusedVertices();
mesh->Cleanup(true);
mesh->CullDegenerateFaces();
mesh->CullUnusedVertices();
RhinoApp().ActiveDoc()->AddMeshObject(*mesh);
RhinoApp().ActiveDoc()->DeleteObject(go.Object(0));
AlignVertices?
Combine works if you have duplicated vertices.
Honestly, I don’t know what’s going on here, because this mesh can’t explode, which means it’s a single mesh, but it has this problem, But there is an edge that divides it in two 
Before getting into cpp are you are able to clean mesh using rhino commands?
Yes, I have run _MeshRepair command to repair.
And rhino prompts Mesh has 13 pairs of faces that intersect each other.
So I think the most important part of is how do I find these faces quickly.
For self intersection I think there is barely any method to do mesh repair both in cpp and standard methods.
Knowing this, how did you generate this mesh?
