Segments can be configured as fixed diameter segments or as variable diameter segments. Fixed diameter segments, such as semirigid tubing that the wire bundle is routed through, do not change as wires and cables are routed, unrouted, or deleted. The diameter of variable segments automatically update as wires and cables are added or removed.
By default, segment diameters update automatically as wires are routed, unrouted, or deleted from the segment.
The segments update accordingly.
When the Defer Update option is enabled, the segment diameters do not update until Update is selected on the the Quick Access toolbar.
