Many of the operations that change the hierarchical structure of a CPN can easily be undone or redone using the Redo tool and Undo tool.

For example, if the Delete element tool is used to delete a subpage tag, then the connection between a substitution transition and a subpage is broken, port/socket assignments are removed, and instances of the subpages are removed. (More information is available about removing hierarchical constructs). However, by simply applying the Undo tool, it is possible to fully reestablish the relationship between the subpage and the substitution transition.
