Get and Set Beams and Joints Example (VB.NET)

This example shows how to get and set beams and joints.

' 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 part exists.
' 4. Ensure that the specified material library exists.
' 5. Open the Immediate window.
' Postconditions:
' 1. Creates static study, frame.
' 2. Prints beam information to the Immediate window.
' 3. Applies Plain Carbon Steel material to all beams.
' 4. Calculates joints for all beams and displays a neutral axis for
'    each beam.
' 5. Prints the pinball tolerance value and unit to the Immediate window.
' 6. Creates a mixed mesh and prints its type and state to the
'    Immediate window.
' *  Creates beam elements by default for parts with structural members.
' *  Because the part document is used elsewhere, do not save any changes.
