Create a library symbol
Create a library symbol
AutoCAD Electrical uses stock AutoCAD blocks and attributes in its library
symbols. The symbols can be any size and width. You do not have to edit an
external support file or database to register a symbol for use in an AutoCAD
Electrical wiring diagram drawing.
NOTE You can also use the Symbol Builder tool, but the quickest way to create
a symbol might be to start with an existing AutoCAD Electrical compatible symbol.
Start with a copy of a similar type and then modify to suit. Avoid deleting the
existing attribute definitions. Reposition and edit their default values as required.
1 Open a new drawing using the appropriate symbol name.
2 Insert an exploded copy of an existing AutoCAD Electrical symbol that
somewhat resembles what you need in the new symbol. Consider 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 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 a
project name 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 the file name of the new symbol using Type it on the
main icon menu page.
