Removing a Superclass

To remove a superclass from a class:

  1. Highlight the subclass in the Class Relationship pane
  2. Highlight the superclass you want to remove in the Superclasses pane immediately below the Class Relationship pane.
  3. Click the Remove button at the top right of the Superclasses pane.
    The superclass remains in the knowledge base, but the superclass/subclass link is broken.

You can only remove a superclass if the class has more than one parent. The subclass still appears in the knowledge base as a subclass of its other superclass(es). If the class has only one parent, the Remove button is disabled.

For example, to remove Person as a superclass of Columnist in the Newspaper knowledge base:

  1. Highlight Columnist in the Class Relationship pane
  2. Highlight Person in the Superclasses pane
  3. Click the Remove button at the top right of the Superclasses pane.

Columnist has multiple superclasses in this knowledge base, so it remains a subclass of Author. Note that a subclass such as Columnist loses its icon when it no longer has multiple superclasses.

To delete a class from the knowledge base, highlight the class and click the Delete class button. See Deleting a Class.
