Emailing drawings
As with any other fi les which are composed of data, AutoCAD drawings
can be sent by email as attachments. If a problem of security of the
drawings is involved they can be encapsulated with a password as the
drawings are saved prior to being attached in an email. To encrypt a
drawing with a password, click Tools in the Save Drawing As dialog and
from the popup list which appears click Security Options… ( Fig. 20.1 ).

and enter the password in the Confi rm Password dialog which appears.

drawing by the person receiving the email (Fig. 20.3).
