Get and Set Datum Example (VB.NET)

'---------------------------------------------------------------------------
' Preconditions:
' 1. Open:

' <SolidWorks_install_dir>\samples\tutorial\dimxpert\bracket_auto_manual.sldprt
' 2. Select a face.
' 3. Open an Immediate Window in the IDE.
' 4. Ensure that the latest SolidWorks DimXpert interop assembly is referenced:
'    a. Right-click on the project in Project Explorer.
'    b. Select Add Reference.
'    c. Click the Browse tab.
'    d. Find and select <SolidWorks_install_dir>\api\redist\swdimxpert.dll.
' 5. Click F5.
'
' Postconditions:
' 1. Inspect the Immediate Window.
' 2. Observe Plane1 and datum G on the DimXpertManager tab.
'
' NOTE: Because this part is used in a SolidWorks online tutorial,
'       do not save any changes when you close it.
