By splitting implemented interfaces you can move selected methods, attributes and events to a new interface. See also: Class Diagram.

1. Create a new interface as described in Creating Interfaces.
2. Select the interface from which you want to move the components.
3. Define the interface you created as the component interface. Proceed as described in Nesting Interfaces.
4. Move the appropriate components from the original interface to the component interface. Proceed as described in Moving Interface Components to a Component Interface.
5. Remove the interface nesting as it was only defined for the move operation.
