This example presents step-by-step instructions for customizing a drag-and-drop rule, according to the Generalization relationship created between classes after the drag-and-drop.

1. Create a profile diagram.
2. Create a class, and name it Class onto Class.

3. For the Class onto Class class, apply the «DragAndDropSpecification» stereotype .

   New Button

   There is a new button in the Profile diagram palette - Drag and Drop Specification. Use this button to create a class element with the assigned «DragAndDropSpecification» stereotype.

   • For the Relation Action Result property, specify the Generalization metaclass. 
   • For the Representation Text property, specify the name of the rule, for example, Create Generalization.
