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

This macro returns the same data returned by the Tools > Check dialog box when the checkboxes, Maximum edge gap and Maximum vertex gap, are selected. This macro uses IEdge::IsTolerant to determine whether common edges are within tolerance of one another. This macro uses IVertex::IsTolerant to determine whether common vertexes are within tolerance of one another. This macro iterates over each edge and vertex in a part and reports the following:

       *  whether the edge or vertex is:

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

           b. 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 gap (or tolerance) in mm for the part

       *  maximum vertex gap (or tolerance) in mm for the part

'----------------------------------------------------------------------------

' 1.  Open a part that contains gaps between common edges and/or vertexes

'     (e.g., <install_dir>\samples\tutorial\assemblymates\head.sldprt).

' 2.  Open an immediate window to view runtime messages.

' 3.  Run this macro.

' 4.  Move cursor across the part in the SolidWorks window.  

'     The tolerant edges and vertexes are selected in each body of the part,

'     and tolerance data for all edges and vertexes is printed in the

'     Immediate window.
