About virtual parts in Cable and Harness

About looms

Looms are the only virtual part type that you can assign to multiple segments. You can also assign more than one loom to a single harness. Because of this, looms are assigned an order and an ID for tracking purposes.

Loom order is based on when and where the loom is placed in the harness. For example, you can place a piece of shrink tubing on a bundle of wires (loom order of 1), and the bundle of wires in a mesh braid (loom order of 2). Loom order also determines the size of the loom to attach.

Looms are named using the Loom ID along with a portion designator. A portion designator is needed when you assign a single loom to multiple segments. For example, if you assign one loom to two contiguous segments which make up a longer bundle of wires, the loom is divided into more than one portion. You can assign each portion to a different segment. If the loom assigned to the two segments had a Loom ID of Loom1, the first loom portion occurrence is named Loom1:1 and the second Loom1:2. Loom ID also links the individual looms from each segment so the BOM counts it as one piece with a cumulative length of all segments.

To indicate that a loom is assigned to a segment, cable wire, or wire, you can determine whether to display the harness object using the loom appearance or the object appearance. By default, all harness objects that have a loom assigned are displayed using the loom appearance. You can also set loom display on individual segments, cable wires, and wires.

You can assign virtual parts to various objects in a harness assembly to provide a complete representation of harness objects in the bill of materials. You can use one of the virtual parts in the Cable and Harness Library, or you can create and use your own. The virtual parts in the Cable and Harness Library include labels, looms, plugs, seals, and terminals.

The text included in a label is specified in the library definition. By adding text on the library definition for a label, you can specify the label text once, and place that label multiple times. You can also override this definition to customize the text on the individual occurrences.
