Get Maximum Edge and Vertex Gaps Example (VBA)

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

' 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 tolerant (distance to neighbor is greater than 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

'

'  Do the following:

'    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.
