With the modeling tool's new version UML Association Class can now be modeled in a Concept Modeling diagram. An Association Class is a model element with both Association and Class properties. You can look at an Association Class as an Association that also has Class properties, or as a Class that also has Association properties. Additionally, it connects a set of classifiers, and defines a set of features belonging only to the relationship and not to any of the classifiers.
Before creating an Association Class between Class elements in your diagram, make sure the Experimental Features options is enabled. Once the option is enabled, please follow the steps below.
