You can reuse UML elements of the Occurrence or Group type.
To reuse UML objects in ARIS Architect/Designer you have to define object links in ARIS UML Designer. Object links specify which UML element created in ARIS UML Designer can be linked to which ARIS item in ARIS Architect/Designer.
In this way, mapped items can be copied to ARIS models within the same database if these models provide an appropriate symbol for the mapped object type.
In ARIS UML Designer, the reused link is listed on the Reused objects page of the object's Properties dialog.
