TECHNICAL ENGLISH
A CAD drawing is produced faster,
is easier to make changes in and
is more accurate. Furthermore, it
requires less manual skills, it is
automatically set to standards and
conventions, and drawings can be
saved and stored electronically which
means it is easy to transmit to the
computer-controlled machines that
will be used to make the product.
