Unify Normals

The UnifyMeshNormals command changes the normal direction of the faces in a mesh object so they all point in a consistent direction.

This helps repair meshes for rapid prototype printing.

Steps

Note

Example

  1. Import an STL file with holes in it.
  2. Fill the holes in the mesh.
  3. Weld the mesh setting the welding angle to 180 to make sure all vertices get welded.
  4. Use UnifyMeshNormals.
  5. Turn on one sided rendering and shade the model to see if the mesh face normals point in or out.
    If you see inside the mesh, normals point the wrong way.
  6. Use the Flip command to change the mesh normal direction if necessary.
  7. Export in desired format.
