How to Split a Control Flow in Activity Diagram?

When you found an action missing and you want to add it back into an activity diagram, you can make use of the split feature to easily insert the action shape back to a control flow. The insertion of action shape will result in the creation of new flow that connects the new action shape and the "to-shape" that is originally connected by the original flow. The original flow will be updated to connect to the new shape. In other words, the details specified to the original flow, if any, will remain intact.

To use the split resource:

1. Move your mouse pointer over the control flow to which you want to add the action shape.
