Set Tolerances and Compare Geometry (VB.NET)

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

' This example shows how to set the tolerances and then compare the volume and geometry

' of two versions of the same part and save the volume comparison results as a solid 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 on the project in Project Explorer, Add Reference,

'     Browse to <SOLIDWORKS_install_dir>\api\redist\CLR2,

'     select Solidworks.Interop.gtswutilities.dll).

' 3. The specified files exist.

' 4. C:\test\ exists.

'

' Postconditions:

'

' 1. Geometry comparison report, C:\test\Report\gtReportIndex.htm, is created.

' 2. Position and angular tolerance statuses display in the Immediate Window.

' 3. Face and volume comparison statuses display in the Immediate Window.

' 4. Volume comparison part, C:\test\volumeComparison.sldprt, is created.

'

' NOTE: Do not save the parts as they are used in a SOLIDWORKS tutorial.
