I have some Oracle Tables with foreign keys constraints but when I add them to Data Modeler, the relationships between the tables don't show.

Does anyone know how to do that please ?
I see you are working in SQL Developer - what version?
How do you import those tables? Using drag&drop or using import wizard - are both tables imported at once or in two steps?
