Attributes
You can edit the values of Block
attributes in this editor. Changes apply to the current instance of the
block.
Attributes can be created automatically when you import blocks from
AutoCAD files, or manually when you assign an Attribute name
when you edit a note in a block.
Attributes in SolidWorks drawings can have
multi-line values (note text). However, if you plan to export blocks to
AutoCAD, you should use only single-line values.
To access the editor, select a block in a drawing document and click
Attributes under Text/Dimension
Display in the Block
PropertyManager. Attributes
is unavailable if the block has no attributes.

You can add an attribute to the note, "FW" |
The following columns appear in the editor:
Name.
The name of the attribute (Attribute
name in the Note PropertyManager).
Value.
The value, or text, of the attribute. You can edit the value if the attribute
is not Read Only.
Invisible.
This column contains an X if the
attribute is invisible (information only).
Read Only.
This column contains an X if the
attribute is read only (information only).
Values that are linked to file properties
or custom properties display the link path and variable name ($PRP:"SW-File
Name", for example) during editing but show the values of
the properties (WIDGET, for example)
when blocks are displayed drawings.
