Removing a Superclass
If a class has more than one superclass, you can remove one or more of its superclasses. You must leave at least one superclass. The subclass still appears in the knowledge base as a subclass of its other superclass(es).
Note:
If the class has only one superclass,
the Remove Superclass
(
) button is disabled.
Removing a Superclass
To remove a superclass from a class:
Highlight the class that you want to work with in the Class Browser. The superclasses of the selected class will be shown in the Superclasses pane immediately below the Class Browser.
Highlight the superclass you want to remove in the Superclasses pane.
Click the Remove Superclass (
) button
at the top right
of the Superclasses pane.
The superclass will remain in the knowledge base,
but the superclass/subclass link will be broken.

Class Browser with Columnist highlightedHighlight Employee in the Superclasses pane.
