The Decomposition menu item under the Draw menu allows you to automatically generate symbols. There are three submenu items under this command: Functional Decomposition Diagram, Diagram Hierarchy Diagram, and Diagram Explosion Diagram. Each of these options produces a different view of the current encyclopedia.

When you select any command from the submenu under Draw, Decomposition, a Select for Automatic Decomposition dialog box is displayed. Refer to the specific type of decomposition you want for details.
