You must create assembly-level wire features to define the underlying geometry for modeling connectors. The wire feature contains wires connecting points from the assembly in the current viewport or connecting points from the assembly to ground.
In the Interaction module, select ConnectorGeometryPoint-to-Point Wire from the main menu bar to add a wire feature. You can add disjoint wires, chained wires, or wires that are connected to ground. When you create the wire feature, you can create a geometry set that includes all of the wires in the wire feature to use during subsequent selection procedures; for example, when you select wires for the connector section assignment definition.
Once created, wire features on an assembly cannot be modified directly. If you want to change the points that are connected, you must delete the wire feature and create a new wire feature connecting the desired points. You can remove wires from the wire feature by selecting ConnectorGeometryRemove Wires From Feature from the main menu bar or by using the tool in the Interaction module toolbox.
For detailed instructions on creating assembly-level wires features, see Adding a point-to-point wire feature, Section 11.23.2.
