Overview of wire numbers
Wire numbers are blocks or attributes inserted on a line wire entity. AutoCAD
Electrical assigns each wire number type to its own layer. You can assign a
different color to each of these layers so you can easily tell them apart. There
are 4 types of wire numbers: Normal, Fixed, Extra, and Signal.
Wire numbers that are free to update when you rerun the Insert
Wire Numbers command. Normal
Wire numbers that are fixed to their current value. They do not
update with subsequent runs of the Insert Wire Numbers com-
mand. Fixed
Extra copies of the Normal or Fixed wire number that are assigned
to a given wire network. A single wire network has one Normal Extra
or one Fixed wire number (but not both) and may have many
extra copies of the wire number inserted at various locations on
the network.
