When routing cable manually, you might want to route a cable into a cable tray at some point along the tray's length. For example, the cable needs to exit a conduit and then enter a cable tray.
You can specify an entry point or exit point anywhere along a cable tray using Set Entry Point or Set Exit Point on the ribbon. PinPoint can be used to assist in precise placement.
For example, if you branch the conduit out of the tray using Route Conduit , the software creates a connection between the conduit and cableway features. Then, when routing the cable, you need to select the cableway that owns the tray, and then do the same for the conduit run in the Select Way Features step. The software recognizes the connection between the cableway and conduit runs, and routes the cable through them.
There is no need to route cable in any specific order. You can pick whatever step you want to start the process and then come back to it later, if required. Incomplete routes can be saved and finished later. Additional cables can even be added while routing. When you click Finish, the runs are saved.
