Add Pin Connector Example (VBA)

This example shows how to add a pin connector to a static 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 type library as a reference (in the IDE,
'    click Tools > References > SOLIDWORKS Simulation version type library).
' 3. Ensure that the specified material library exists.
' 4. Open public_documents\samples\Simulation Examples\pliers.sldasm.
' 5. Open an Immediate window.
'
' Postconditions:
' 1. Opens the model.
' 2. Activates the Ready study.
' 3. Deletes the pin between branches connector.
' 4. Adds Pin Connector-3 to the Connectors folder in the Simulation study
'    tree.
' 5. Prints the properties of Pin Connector-3 to the Immediate window.
' 6. Meshes the model.
' 7. Analyzes Ready.
' 8. Inspect the Immediate window, the Simulation Study tree, and the
'    graphics area.
'
' NOTE: Because the model is used elsewhere, do not save changes.
