Copy attributes
COPYTAG is the optional TAG copy attribute. When AutoCAD Electrical
updates a TAG1, TAG2 or TAGSTRIP attribute, it also looks for and updates
any COPYTAG attributes present on the symbol with a copy of the TAG text.
A special replaceable parameter, "%T", can be encoded onto the COPYTAG
attribute prompt value of the definition. It allows for adding a suffix and/or
prefix to the TAG text. If you need more than one extra TAG copy on a symbol,
name the attributes COPYTAG01, COPYTAG02, and so on. If there is no
prompt value encoded on the attribute definition, AutoCAD Electrical simply
applies a copy of the tag-ID to the COPYTAG* attributes.
For example, you create a large "drive" schematic symbol with a TAG1 attribute
for the tag-ID of the drive. 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 potentiometer graphic of the symbol 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 automatically updates each COPYTAG* attribute
accordingly.
Managing Library Symbols
Substitute symbols in the library
You can temporarily substitute an altered symbol for a symbol that is found
in the standard library. Put the .dwg file of the altered symbol in your USER
subdirectory (right-click a project name 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 before 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 get a copy of the original version of the block. Use the Swap/Update Block
command in AutoCAD Electrical to make the change.
