VP ontoUML plugin: how-to add <<relator>> class to <<material>> relation

Question

Using Visual Pradigm v17, OpenJDK v11.0.10, OntoUML plugin 0.5.3 on MacOS 10.16:

I'd like to use the relator class in my model. I cannot find a way to manually connect the relator class to the material relation that it is supposed to specify.

I tried to draw a connection, just like e.g. a specialisation or association relation, from the relator class to the material relation. I tried several different options of those that are being presented, but without success.

Answer 1

After muddling with this over an extended period, I feel stupid to see the solution to this.

1. Add an association class duh by right-clicking the canvas and selecting Add Shape > Association Class
2. Select the mediation relation that it should specify.
3. Done

I can't believe that I missed this obvious way forward
