Surface Mesh Enhancement Options: Advanced Tab
Tolerance
Internal Tolerance: This is the tolerance that the surface mesh enhancer will use to make elements between feature lines and to match up nodes.
Dangling Features
Delete Feature: If the surface mesh enhancer cannot extend the feature segment, it tries to remove dangling feature segments. It will remove a feature segment if the planar angle creating the segment is less than the Delete Feature field (in degrees).
Continue Feature: Dangling feature ends can cause meshing problems. The surface mesh enhancer first tries to extend the feature segment if it can find triangle edges that are within the Continue Feature field. If it cannot extend feature segments until they connect to another feature, it tries to remove dangling feature segments.
Features for Files
The following commands generate meshes in the Superdraw format. To view these files, use 
Open and set the Files of Type to Autodesk Simulation Superdraw III (*.esd).
Front.esd Only: This will create the front.esd file.
Input.esd Only: This will create the input.esd file. The input.esd is original surface mesh, converted to triangular elements, with the layer numbers changed to show which lines are feature lines and which ones are the normal mesh.
