notified each time a digital signature containing your digital ID is
attached to a file.
■ High. Use a High security level if the signature is very sensitive and you
do not want your computer to be misused in the signing of a file. You are
prompted for a password each time you sign a file.

Attach a Signature to a Single File
When you attach a digital signature to a file, you are helping to ensure that
recipients of the file are notified of modifications.
You can set an option for a signature to be attached after you save a file. A
single digital signature can be attached per file.
If you plan to protect a set of drawings with a password and a signature, first
add the passwords, and then sign the files in a batch. Adding a password to
a signed drawing, or otherwise changing a signed drawing, invalidates the
signature.
Note Unless you use the Attach Digital Signatures utility, you must individually
sign each drawing.
To set an option for a signature to be attached after you save a file
1 Do one of the following:
■ On the Tools menu, click Options, and then in the Options dialog box,
on the Open and Save tab, click Security Options.
■ On the File menu, click Save As, and in the Save Drawing As dialog box,
on the Tools menu, click Security Options.
