Apply Table-driven Load to Multiple Beams Example (VBA)

This example shows how to apply a table-driven elliptical load to multiple beams on a part.

'---------------------------------------------------------------------------
' 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. Open the Immediate window.
' 4. Ensure that the specified part exists.
'
' Postconditions:
' 1. Applies a table-driven elliptical load to the part
'    and prints its type and other force-related values
'    in the Immediate window.
' 2. To verify, examine the External Loads folder
'    in Study 3 in the Simulation tree.
' 3. Examine the Immediate window.
'
' NOTE: Because this part document is used elsewhere,
' do not save any changes when closing it.
