You need to introduce an additional node to which you reference from the entity and reference back to the entity. <br /> __________ <br /> | Entity |<br /> |___________| <br /> /|\ |<br /> | \|/<br /> |_____O New Node<br /><br />Have a look at the UML example there you find a class called associationnode in the class diagram that is what you need to implement in your scenario. <br /><br />Best wishes, ThomasThomas Off2019-04-30T11:05:59ZSelf-RelationChristos trikalishttps://www.adoxx.org/live/c/message_boards/find_message?p_l_id=&messageId=15183412019-03-29T09:25:11Z2019-03-29T09:16:31ZHello all,<br />How can i define the source and destination of a relation class to point to the same entity?<br /><br />for example __________ <br /> | Entity |<br /> |___________| <br /> /|\ |<br /> |_____|<br /> <br />Thank you in advanceChristos trikalis2019-03-29T09:16:31Z
