You create the assembly-level wire features, connector sections, and connector section assignments in the Interaction module to model a connector. You should create the desired reference points and datum coordinate systems before you begin modeling the connector. The Model Tree, shown in Figure 21–6, is helpful for understanding the organization of the reference points, datum coordinate systems, and wire features that you created in assembly-related modules, as well as connector sections and connector section assignments that you created in the Interaction module. You can use the Query toolset in the Interaction module to obtain connector assignment information for selected wires.
