You can show implicit connections of overlapping objects if you want connections to be visible even though the relevant objects overlap.
Prerequisite
You have enabled the Create implicit connections for overlapping objects check box (ARIS > Options, Selection tab, option Model > General > Objects).
Procedure
Place an object on another object to which it already has a connection, either completely or overlapping. The Create relationship dialog opens. The Connection occurrence check boxes of the existing connections are enabled. If you drag objects that are not yet linked via connections on top of one another, you cannot disable the setting for the Hide check box in the Create relationship dialog. This means that they will be hidden in any case. You can disable the setting once the objects and connection have been saved.
In the row for the existing connection disable the check box of the Hide column.
Click OK.
The corresponding connection is displayed even though the objects overlap.
