Sign Drawings | 785
Digital signatures work on files that are compatible with the AutoCAD 2004
and AutoCAD 2000 drawing-file formats. If you receive a signed file and save
the file, it is considered modified, and the signature is invalidated. However,
you generally can still view information about it. If you receive a signed
AutoCAD 2000 drawing-file and save the file, the signature information can
be lost.
Note If the SIGWARN system variable is on and you open a file with a valid sig-
nature, the digital signature status is displayed. If SIGWARN is off and you open
a file, the digital signature status is displayed only if a signature is invalid.
You can also view the properties of a drawing file in Windows Explorer to
examine and validate a digital signature. Some operating systems display a
modified icon for a drawing that has a valid digital signature attached. If the
modified icon is displayed, your computer may slow down (depending on
processor speed and file size), so you can turn off the display.
To validate a signature when opening an AutoCAD file
1 On the Tools menu, click Options.
2 In the Options dialog box, on the Open and Save tab, select the Display
Digital Signature Information option.
3 Click OK.
4 Open a file compatible with the AutoCAD 2004 or AutoCAD 2000
drawing-file format that has a digital signature attached.
The Digital Signature Contents dialog box is displayed. The dialog box
provides information on the status of the file and the signer.
5 In the Other Fields list, select from the list to view details of the digital sig-
nature, such as the issuer, beginning and expiration dates of the digital ID,
and the serial number.
6 Click Close.

provides information on the status of the file.
