on the attribute definition, AutoCAD Electrical simply applies a copy of the
tag-ID to the COPYTAG* attribute(s).
For example, you create a large "drive" schematic symbol with a TAG1 attribute
for the drive's tag-ID. You want some other parts of this single symbol to carry
the TAG1 value plus a suffix like "-POT" and "-DBRES". On your library symbol,
insert an attribute definition "COPYTAG01" with a prompt value of "%T-POT"
near the symbol's potentiometer graphic and "COPYTAG02" with a prompt
value of "%T-DBRES" near the dynamic braking resistor graphic. When this
symbol is inserted on a schematic drawing, and a TAG is assigned, AutoCAD
Electrical will automatically update each COPYTAG* attribute accordingly.
Substitute symbols in the library
You can temporarily substitute an altered symbol for a symbol that is found
in the standard library. Put the altered symbol's .dwg file in your USER
subdirectory (right-click inside the Project Manager and select Settings to find
the full path). The AutoCAD Electrical component insertion command always
looks at this directory for the requested symbol prior to going to the selected
symbol library.
NOTE AutoCAD Electrical uses regular AutoCAD blocks. If you insert a block from
one library and then try to insert the same block name from a different library,
you'll get a copy of the original version of the block. Use AutoCAD Electrical's
Swap/Update Block command to make the change.
Change appearance of existing library symbols
The AutoCAD Electrical default symbol library is installed in the /Program
Files/Autodesk/Acade {release#}/libs/jic1 subdirectory (and /Program
Files/Autodesk/Acade {release#}/libs/jic125 for a uniform 0.125 text height
library). You can modify the ".dwg" version of each symbol to comply with
your specific standards or client requirements.
1 Open each symbol up in its native AutoCAD .dwg format (using File ➤
Open).
