Well as the title says, i would like someone could post an step by step or "mini-how to" in order to include nary relationships in a class diagram using Papyrus.

Also would be nice to add also a association class (if its possible) like date in relation manage in the example below or quantity in the provide association.

Thanks in advance

Some classic examples:

index.php/fa/32409/0/

Example using association class quantity:

index.php/fa/32412/0/

Hi Eduardo,

You should start with a simple binary association, then add "Association branches" to connect the remaining nodes:

index.php/fa/32413/0/

HTH,

Hi,

Association class should be drawn first (Instead of creating a binary Association, you create a Binary AssociationClass). However, it seems that NAry Association Classes don't work well (The diamond is displayed as a square, and the dashed-link from the AssociationClass disappears).

Cheers,
Camille
