In Studio 7.0 and earlier versions, General Flow Diagrams were named Activity Diagrams: If you created Activity Diagrams in Studio version 7.0 or earlier and have upgraded, your Activity Diagrams are now called General Flow Diagrams in Modeler.
Studio 7.1 included new Activity Diagrams, which you should use in preference to General Flow Diagrams. General Flow Diagrams are being deprecated and are included in Modeler only for backward compatibility.
Should you need to create General Flow Diagrams, they can now be created only from the Model or a Package. After creating a General Flow Diagram you can drag it to an Activity, Actor, Class, Data Type, Event, Interface, Operation, Subsystem or Use Case.
