used on a new project but the client likes his limit switches drawn a bit
differently. Simply make client-specific versions of the limit switch symbols.
Then use the Update option; select any limit switch on the drawing, and
then reference the path to the new version of the symbol. AutoCAD
Electrical quickly replaces all instances of the symbol it finds on the
drawing(s) with the new version of the same symbol. The Library mode
works the same way as the Update mode, but will swap out all the blocks
on the drawing(s).
When you swap or update a block there may be times when you want the
values of certain attributes mapped to different attribute names. For example,
you may be doing a Library Update and the library symbols you are swapping
out do not use standard AutoCAD Electrical attribute names. You want a quick
way to update the library symbols, but you do not want to lose information
held on the current attributes.
