you assign to this attribute definition at the library symbol level (that is, ".dwg"
file of the symbol opened and displayed in AutoCAD) becomes the family
code character string AutoCAD Electrical uses to build the tag name of the
component when the block is inserted into your wiring diagram. This default
value character string is used as the Family Code (%F) portion of the tag format
code of the drawing you set up in the Drawing Properties Components
dialog box (example %F%N).
For example, use "PB" for a default value of the attribute definition TAG1 if
the family name you want AutoCAD Electrical to use is "PB" (examples:
"PB100", "100-PB", "PB4-100"). You can override this family name at component
insertion time, a later edit, or automatically by use of the "wd_fam.dat "
mapping file.
NOTE If the TAG1 attribute carries no default value then AutoCAD Electrical uses
the FAMILY attribute value of that symbol.
Overview of child component attributes (TAG2)
AutoCAD Electrical puts a copy of the parent tag name of the component on
the child component attribute (TAG2). During the AutoCAD Electrical tagging
operation, AutoCAD Electrical takes the parent tag name of the coil (carried
on its TAG1 attribute) and copies it to the TAG2 attribute of this contact. If
no parent tag is found then AutoCAD Electrical displays the attribute default
value of the definition.
Panel attributes
Overview of panel attributes
AutoCAD Electrical does not have attribute or naming requirements for the
mechanical footprint block symbols. As AutoCAD Electrical inserts a footprint
symbol into the drawing, it copies various data to the footprint block such as
component/device tag name, description, manufacturer code, and catalog
number. It first looks for target attributes to copy the data to. If not found,
AutoCAD Electrical simply inserts the schematic values as standard AutoCAD,
nonvisible extended entity data (Xdata).
Some manufacturers provide free, to-scale mechanical libraries of their control
components, all in AutoCAD format. Or you may have your own in-house
footprints set up. In either case, since AutoCAD Electrical does not have naming
