I'm try to figure out if there's a way to create SysML connectors without an IBD?

The reason for this question is that i'm writing a macro using the API to generate connectors, but I'm struggling to figure out how to relate the connector ends with a part property.

Right now I create a connector with ElementsFactory, set the Client and Supplier, and then the only way I know of to associate the ends with a partproperty is to use the createPathElement() method in the PresentationElementsManager class, which requires me to create symbols for the part properties on an IBD.

Is there some way to creating these "Path Elements", which to be honest I'm not even sure what they without creating an IBD? Maybe I just need a better understanding of what "Path Elements" are, so I understand better how they are associating the connector ends with a part property.
