Avoid putting wire pigtails on your new symbols. Pigtails can defeat the
AutoCAD Electrical SCOOT command and automatic wire numbering when
two symbols with pigtails bump up against each other. A wire connection
pigtail is mandatory when you insert a short pigtail at a wire connection point
that has no other visible symbol geometry nearby since AutoCAD Electrical
must see something tangible on a symbol at a wire connection point.
Symbol origin
The AutoCAD Electrical library symbols generally have their origin points
centered between the first (or only) pair of wire connection point attributes.
Though it is not mandatory, it helps AutoCAD Electrical determine the correct
orientation for alignment with an underlying wire at insertion time.
Symbol width
There are no restrictions. Every symbol can have a different width. At insertion
time the width of the symbol is determined by reading the locations of its
wire connection attributes (attributes with name X?TERMn).
Wire connection points
A symbol can have hundreds of connection points and a terminal pin number
attribute tied to each (use suffix codes beginning with "01" and ending with
"ZZ").
Component description text
You can insert three lines of description text up to 60 characters long. The
attribute names are DESC1, DESC2, and DESC3 and generally appear on both
parent/stand-alone and child contact symbols. You can insert additional
DESCn attributes on your symbol and edit them with any attribute editing
tool, but AutoCAD Electrical does not process them.
Symbol Builder
Symbol Builder
Defines new AutoCAD Electrical component, terminal, and panel layout library
symbols.
You can convert symbols or create custom components on the fly. Symbols
created or converted using Symbol Builder are fully compatible with AutoCAD
Electrical. They break wires upon insertion, and appear in the bill of material
and various component and wire connection reports.
