Add Rigid Connector Example (VB.NET)

This example shows how to add a rigid connector to a frequency study.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in (in SOLIDWORKS, click 
'    Tools > Add-ins > SOLIDWORKS Simulation > OK).
' 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference
'    (in the IDE, click Project > Add Reference > .NET > 
'    SolidWorks.Interop.cosworks > OK).
' 3. Ensure that the specified model document exists.
' 4. Open an Immediate window.
'
' Postconditions:
' 1. Opens the model.
' 2. Gets the Ready frequency study.
' 3. Adds Rigid Connector-1 to the Connectors folder in the Simulation study
'    tree.
' 4. Prints the properties of Rigid Connector-1 to the Immediate window.
' 5. Meshes the model.
' 6. Analyzes Ready.
' 7. Prints the resonant frequency of each mode to the Immediate window.
' 8. Inspect the Immediate window, the Simulation Study tree, and the
'    graphics area.
'
' NOTE: Because the model is used elsewhere, do not save changes.
