Create Simulation Gravity Feature Example (VBA)

This example shows how to create a simulation gravity feature in a motion study.

'---------------------------------------------------------------------------
' Preconditions:  
' 1. Verify that the specified model document exists.
' 2. In SOLIDWORKS, verify that View > MotionManager is selected.
' 3. In the IDE, click Tools > References and select
'    SOLIDWORKS version MotionStudy Type library.
' 4. Click OK.
' 5. Open an Immediate window.
'
' Postconditions:
' 1. Adds Gravity to the MotionManager design tree on the Motion Study 1 tab.
' 2. Inspect the Immediate window.
'
' NOTE: Because the model is used elsewhere,
' do not save changes when closing it.
