To remove a superclass from a class:
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:
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.
