To move or copy a class from one level of the model hierarchy to another in the Model navigator, drag the class to another location.
Use the following rules and guidelines when you move or copy classes:
If you drag a class from one level of the hierarchy to another for the same model, Metadata Manager moves the class.
If you drag a class from one custom model to another custom model, Metadata Manager copies the class.
If you move or copy a class, Metadata Manager moves or copies all subclasses for the class.
You cannot drag classes into packaged or universal models.
To move a class:
In the Model navigator, select the class you want to move or copy.
Drag the class to another location.
If the location to which you want to move or copy the class is collapsed, move the pointer over the parent class to expand the child classes in the navigator.
