Get Forces and Stresses for Selected Beams Example (VBA)

This example shows how to get the force load and stress values for structural members.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in
'    (in SOLIDWORKS, click Tools > Add-ins > SOLIDWORKS Simulation).
' 2. Add the SOLIDWORKS Simulation type library as a reference
'    (in the IDE, click Tools > References > SOLIDWORKS
'    Simulation version type library).
' 3. Open the Immediate window.
' 4. Open install_dir\samples\tutorial\api\weldment_box3.sldprt.
' 5. Select the Simulation study tab called frame.
' 6. Click the Run button on the Simulation CommandManager to
'    refresh the study results.
' 7. Click Yes in the dialog box.
' 8. In the Simulation Study tree, select SolidBody1(Structural Member1[3]).
' 9. Run the macro.
'
' Postconditions: The load forces and stresses for the selected beam are listed in
' the Immediate window.
