A cable is a bound or sheathed group of mutually insulated conductors. When working with cables, the software lets you choose the specific cable type required.

Cable Run

The length of a cable, from start to finish, is called a cable run. A cable run defines the relationship of the cable to other objects in the model, such as electrical cabinets and equipment.

Parallel Cables

You can create parallel cables by entering a number greater than 1 for the Parallel Cables property on the Cable Properties dialog box. The software then creates a parallel cable (parent) and multiple paralleled cables (children). For more information, see Cable Properties Dialog Box.

Autorouting Cable

You can automatically route cables using AutoRoute on the Edit Cable Path ribbon. After you define necessary cable properties, originating and terminating equipment information, the software routes the cable along the shortest path through the cable trays or conduits. If necessary, you can modify the autorouted path by specifying additional must-include cable trays or conduits for the selected cable.

You must assign a signal type for the cable, cable trays, and conduits to autoroute cables.

Editing Cable Path

After the software automatically routes the cable, you can edit the cable path so that the cable runs through the selected cable trays and conduits. To define the path manually, select the entry point, the way features through which the cable should pass, and then the exit point.

If you do not have cableways and conduit in your model, use the Route Cableway and Route Conduit commands to create them.

Max Fill

As you route a cable, you can view the maximum fill for the cable tray or conduit by checking the Max Fill box on the ribbon. If you click Max Fill, the software highlights the corresponding tray or conduit containing the maximum fill. The software also calculates the maximum fill during the autorouting process. You can allow overfilling of the cable trays or allow real-time fill calculations during the routing process.

Fill calculations are based on the National Electrical Code (NEC) standard. The software performs the calculations using a Microsoft Visual Studio module that can be customized based on the project requirements.

  • You can use surface style rules to show which cable trays are full and which trays are nearly full.

  • You can run a cable fill report for cable trays and conduits.

Place Cable Markers

Cable markers are placed on cableways or conduit features to designate the path of the cables. After being placed, the cable markers can be used to describe a cable path on a cable-routing report.
