Detect and Visualize Bad Mesh Features

Open Live Script

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.
