Enhancements / Additions:

• Discrete geometry functionality.  This functionality will allow the generation of a new surface grid using the original triangulation as the underlying geometry.  The topology is automatically extracted based on features identified in the discrete triangulation and on existing topological boundaries specified in the triangulation.  Once the topology is extracted, geometric surfaces are constructed and can be used like traditional NURBS-based geometric surfaces.  The command line option for this action is -discretegeometry or -dg.
  Two parameters are used during the feature identification: dihedral angle and open angle. 
  1. The dihedral angle is the angle between adjacent boundary faces.  Edges with dihedral angles greater than the specified threshold will be considered candidate features.  The dihedral angle threshold can be specified via the command line using either the -dihedralangle or -da options.
  2. The open angle threshold is used to identify corners.  Those having an open angle greater than the specified threshold will be considered candidate features.  The open angle threshold can be specified via the command line using either the -openangle or -oa options.
• Added function to display the normal vectors for boundary faces of a surface mesh under the Debug panel.
• Added command line option -stoltol used to specify the tolerance used for the coincident node when processing STL files.
• Automatically decrease the surface resolution for models containing more than 5,000 surfaces.
• Vectors automatically re-scale when the view is reset in order to keep their size on the same order has what is being displayed.

• Corrected bug that caused SolidMesh to crash if the Fileio Read File or Write File dialog boxes were closed using the window close button.
• Corrected bug in the STL file reader.
• Corrected bug that created zero length vectors when working with discrete data, i.e. grid files.

• Trimming IGES-tagged periodic surfaces.
• Creating a composite surface using discrete geometry surfaces.
