Get Maximum Edge and Vertex Gaps Example (VB.NET)

This example returns the same data returned by the Tools > Check dialog box when the check boxes, Maximum edge gap and Maximum vertex gap, are selected.

This example shows how to iterate over each edge and vertex in a part to obtain:

        *  Whether an edge or vertex is:

            * tolerant (distance to neighbor is greater than 5.0E-9 mm).

            * exact (distance to neighbor is less than or equal to 5.0E-9 mm).

        *  Gap size (or tolerance) in mm of each edge or vertex.

        *  Maximum edge and vertex gaps (or tolerances) in mm for the part.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open install_dir\samples\tutorial\assemblymates\head.sldprt.
' 2. Open an Immediate window.
'
' Postconditions: Inspect the Immediate window for tolerance data for all edges
' and vertexes.
'
' NOTE: Because the model is used elsewhere, do not save changes.
