Set Tolerances and Compare Geometry Example (C#)

his 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 interop assembly as a reference
'    (right-click the project in Project Explorer, click Add Reference > 
'    browse to install_dir\api\redist\CLR2 > SolidWorks.Interop.gtswutilities.dll).
' 3. Verify that the specified files exist.
' 4. Verify that C:\test\ exists.
'
' 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.
