Set Tolerances and Compare Geometry Example (VBA)

This example shows how to set the tolerances and then compare the volume and geometry of two versions of the same part using the SOLIDWORKS Utilities API.

'----------------------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Utilities as an add-in
'    (in SOLIDWORKS , click Tools > Add-Ins > SOLIDWORKS Utilities).
' 2. Add the SOLIDWORKS Utilities type library as a reference
'    (in the SOLIDWORKS Microsoft Visual Basic for Applications IDE, click
'    Tools > References > SolidWorks Utilities <version> Type Library).
' 3. Verify that the specified parts exist.
' 4. Verify that C:\test\ exists.
' 5. Open the Immediate window.
'
' Postconditions:
' 1. Creates a geometry comparison report, C:\test\Report\gtReportIndex.htm.
' 2. Gets position and angular tolerance statuses.
' 3. Gets face and volume comparison statuses.
' 4. Examine the Immediate window, graphics area, and C:\test\Report\gtReportIndex.htm.
'
' NOTE: Because the parts are used elsewhere, do not save changes.
