Create Simulation Gravity Feature Example (C#)

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, right-click the project name in the Project Explorer, 
//    click Add Reference, browse to install_dir\api\redist\CLR2, and select 
//    SolidWorks.Interop.swmotionstudy.dll.
// 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.
