Merges vertices in a mesh
 
 
 

How to merge all coincident vertices in a mesh.

Coincident vertices are merged and normals are averaged at the merged vertices.

This tool is only needed in rare cases. For example, a file imported from a different system, in a format other than STL, could have all its shared vertices stored twice. This could be detected within the Mesh Repair tool by the presence of a red boundary surrounding each triangle. In that case, the vertices must be merged with Mesh Weld Vertices before using any other Mesh tool.

To merge vertices

  1. Choose Mesh > Mesh Cleanup > Mesh Weld Vertices .
  2. Select one or more meshes.
  3. Click the Weld Vertices button in the lower right corner of the window.
