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

s = 
  stlFileChecker with properties:
