consideration the number of wire connection points, rating attributes,
and whether your new symbol is a parent symbol (attribute TAG1) or a
child symbol (attribute TAG2).
3 Clean up the graphics. Keep everything on layer 0.
4 Reuse attribute definitions from the exploded symbol. Reposition them
as required. Make sure that you keep terminal pin number text paired
with its wire connection attribute (the last two digits of each attribute
name must match, "X4TERM01" wire connection point attribute matched
with "TERM01" terminal pin number text attribute).
5 Use DDEDIT to change the TAG1 or TAG2 and the FAMILY attribute
values to the desired family code. Insert any pre-defined terminal pin,
description, or catalog number attribute values.
6 Delete unneeded attribute definitions and graphics.
7 Save your work to the jic1, jic125, or user subdirectory (right-click inside
the Project Manager and select Settings to find the full path). To test it,
call up a new or existing AutoCAD Electrical drawing. Try to insert your
new symbol into an existing piece of wire. You can manually enter your
new symbol's file name using Type it on the main icon menu page.
Tips and Hints
Pigtails
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 very short pigtail at a wire connection
point that has no other visible symbol geometry nearby since AutoCAD
Electrical needs to 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 this is not mandatory, it helps AutoCAD Electrical determine the
correct orientation for alignment with an underlying wire at insertion time.
