// First root configured to use km 

IAgStkObjectRoot root1 = new AgStkObjectRootClass(); 

root1.UnitPreferences.SetCurrentUnit("Distance", "km"); 

 

// Second root configured to use miles 

IAgStkObjectRoot root2 = new AgStkObjectRootClass(); 

root2.Isolate(); 

root2.UnitPreferences.SetCurrentUnit("Distance", "mi"); 

 

// Create new scenario and ship object 

// Close current scenario 

if (root1.CurrentScenario != null) 

{ 

    root1.CloseScenario(); 

} 

root1.NewScenario("Test");

// Obtain references to the ship object from each root 

IAgShip shipFromRoot1 = root1.GetObjectFromPath("Ship/Ship1") as IAgShip;
