showNonManifoldVertices

Highlight non-manifold vertices in STL file or mesh

Since R2021b

    Description

    example

    showNonManifoldVertices(s) displays the geometry contained in the STL file and highlights the non-manifold vertices in red.

    showNonManifoldVertices(m) displays the mesh and highlights the non-manifold vertices in red.

    Use the stlFileChecker object to detect and display bad features in a STL file.

    stlFilename = 'sample_stl_file.stl';
    s = stlFileChecker(stlFilename)
    detected 8 Non Manifold Edges.
    detected 3 Non Manifold Vertices.
    detected 4 duplicate Vertices.
    detected 0 Slivers.
    detected 12 Normal Transition Edges.
    detected 2 Free Triangles.
    detected 9 T-Vertices.
    
    s = 
      stlFileChecker with properties:
    
                     FileName: 'sample_stl_file.stl'
