Protect Drawings with Encryption

If you add a password to a drawing and save the drawing, the drawing is encrypted and cannot be reopened until the password is entered.

You can attach a password to a file while modifying the file or when you save the file. You must individually add a password to each drawing you want to encrypt.

WarningIf you lose a password, your drawing file is lost. Before you add a password to a drawing, you should create a backup that is not protected with a password.
