You can create up to 100 new diagram types in a System Architect encyclopedia. To add a new diagram type, you rename one of 100 generic diagram types available: User 1 through User 100.

You cannot rename a generic user name to an existing diagram name. For example, the following is not valid because “Entity Relation” is already in use:

After a new diagram has been created, it has one default property: Description. There is no need to add any other properties to the diagram; but if you need to, see Adding and changing properties of diagrams.

After you have created a new diagram type, you can assign symbols to it: see Assigning symbols to diagrams.

New diagram types are automatically added to the All Methods tab of the explorer. There is no facility to also add them to other tabs.
