Adding Cabling Components
You can add the following components to a location along the cable path, between the two cable-terminating entry ports:
• Custom components—These are similar to splice components, except that they do not use electrical parameters. Use custom components for cabling objects that do not require a reference designator.
• Splices—These are components added along the length of a cable. The cable name and the length from connector to connector is not affected after the splice component is installed.
• In-line connectors—This is a pair of male and female connectors that break the cable into two physical cables but maintain signal continuity between them. The connector assembly must have an assembly-level coordinate system on either side representing an entry point and an exit point. Placing the connector on an existing cable splits it into two distinct cable segments. The length of each entity is calculated from the entry or exit location point. To add internal lengths, use the entry port parameter int_length on the component.

Insert Components command from the Cabling Data & Components ribbon group to add cabling components to a harness. This tool has three dedicated options:
Insert Components command from the Cabling Data & Components ribbon group to add cabling components to a harness. This tool has three dedicated options:• Insert Custom Component— Add user-defined or non-standard components.
• Insert Splice— Add a splice to connect multiple wires.
• Insert In-Line Connector— Add connectors that join wires in a straight line.
 | Cabling components can only be placed inside a Harness Assembly. |
