You create connectors and connector properties in the Interaction module. You specify a connector name, a connector property, the first and second connector points (or ground), and possibly local orientations for the connector points to define a connector. You should create the desired reference points and datum coordinate systems before you create a connector. The Model Tree is helpful for understanding the organization of the reference points and datum coordinate systems that you created in assembly-related modules. For more information on creating connectors, see “Connector editors,” Section 15.8.6.
