You can change connection alignments later by selecting a different anchor point for the connection on the item.
Procedure
Click the corresponding edge. The anchor points and angles of the connection are marked with a square.
Click the relevant anchor point of the source or target item, hold down the mouse button, and drag the square to the new anchor point.
The connection will be realigned.
Click Connection on the Symbols bar, or click the source object and then the Connection button on the mini toolbar.
You can determine the course of a connection by clicking at the relevant positions in the diagram area while drawing the connection to the target item.
In the model, click the positions via which you want the connection to run. Each click adds an angle. This way, it is possible to lead the connection path around an item.
The connection is aligned.
Open the model properties.
Click Format > Connections on the Selection tab.
If you want to allow only right-angled connections, enable the New connections only right-angled check box.
If you want to allow both right-angled and straight connections, disable the New connections only right-angled check box.
Once you have enabled or disabled the check box, you can create new connections with
the specified connection alignment.
Enable the Use as default check box if you want your setting to apply to all new models. In this case, it is transferred to the options dialog (ARIS > Options, entry Model > For new models > Connections).
Click OK.
The connections will be aligned in the manner specified when they are being created.
