Connection
The "Connection" element consists of an arrow that can be used to connect process elements.
Create a connection
You can find the connection in "Processes" under "Elements." It belongs to the "Other Elements" category. From there, it can be moved to the desired location in the process chain using drag-and-drop. General information on creating process elements can be found here.
The connection does not have a Properties dialog box.
Simply drag the element toward the first element you want to connect to a second element. Then release the mouse button. The connection arrow is created automatically, and its starting point is connected to the first element. Next, drag the arrowhead to the second element to create the connection.
The linked process elements will be processed later in exactly this order.
Process elements can be linked automatically as soon as they are created. You can find all the information you need here.
