Compare Geometry Example (VB.NET)

This example shows how to use the SOLIDWORKS Utilities API to compare geometries in two part documents.

' 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 > SolidWorks.Interop.gtswutilities.dll).
' 3. Verify that the specified files exist.
' 4. Verify that C:\test\ exists.
' 5. Open the Immediate window.
' Postconditions:
' 1. Creates C:\test\Report\gtReportIndex.htm.
' 2. Gets the face and volume comparison statuses.
' 3. Examine the Immediate window, graphics area, and 
'    C:\test\report\gtReportIndex.htm.
' NOTE: Because the parts are used elsewhere, do not save changes.
