    CA" is the acrony& for Co&uter-Aided "esi#n. A CA" syste& is a

    co&bination of hard!are and soft!are that enables en#ineers and architects to desi#n

    everythin# fro& furniture to airlanes.

    A CA" syste& allo!s an en#ineer to vie! a desi#n fro& any an#le !ith the

    AutoCA" is an interactive dra!in# syste& desi#ned to er&it a user to
