This command changes a specified field default value for a selected record format attached to symbol definitions. Symbols already placed on the drawing are unaffected.
To change one record format field:
Select Tools > Records > Change One Field.
The Change One Field dialog box opens.
From the Symbol Folder list, select None, All, or a symbol folder, if any.
Select None to change the record of the symbol definition at the root of the symbol library (symbol definitions not in any folder). Select All to change the record format of all of the symbol definition in the file’s symbol library. Selecting a symbol folder changes all of the symbol definitions only in that folder and any subfolders.
From the Record Format list, select the record format.
The Field Name selections depend on the record format selected.
Select the Field Name to change.
Enter the New Value.
Click OK.
Confirm the operation and the number of symbol definitions affected.
