Add Cyclic Symmetry Restraint Example (VB.NET)

This example shows how to add a cyclic symmetry restraint to a static study.

NOTE: To get persistent reference identifiers (PIDs) for model selections, you can use pidcollector.exe or IModelDocExtension::GetPersistReference3.

'----------------------------------------------------------------------------
' 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.
'
' Postconditions:
' 1. Opens the specified model document.
' 2. Gets study, Partial-Solids.
' 3. Adds the Cyclic Symmetry-1 fixture to Partial-Solids.
' 4. Meshes the model.
' 5. Analyzes Partial-Solids.
' 6. Inspect the Simulation study tree and the graphics area.
'
' NOTE: Because the model is used elsewhere, do not save changes.
