About Cable Symbols
A cable symbol denotes that all wires passing through it are conductors of a single cable. A note on the symbol includes the cable name. The symbol can stretch or shrink to accommodate moved conductors.
Each wire in a cable is required to pass through every cable symbol for the cable. A wire cannot belong to more than one cable. To place a cable symbol on a sheet, all wires in the cable must have at least one segment on the sheet.
All wires must go through a cable symbol in parallel. If some wires are not parallel, Diagram gives you the option to let it automatically create jogs so that each wire can be included in the cable symbol. The following figure displays a cable symbol applied to five conductors.
Use the Electrical Parameters dialog box to modify the cable symbol parameters.
