At the beginning, the CAD
system should be used for simple projects in order to check
out the system and to gain
confidence. If the system is for drawings generation, then
drawings that may have a
lot of revisions are ideal because revising data in a CAD system
is faster and neater than
changing paper drawings. Even if it first takes longer to create
the job or the drawings on
the CAD system than with manual methods, the time saved on
the repetition or revision
cycle should provide a net savings over traditional method or
manual drafting.
Furthermore, inserting “pre-checked” parts, details, notes or other data
into a product or a
drawing can also save some checking time.
The success of CAD is not
automatic. A lot of study, training, and perseverance are
required to make the
system work successfully. Attempts to automate will certainly fail if
operators are not capable
in programming the system, or if planning is insufficient. A
company must learn how to
use library parts, menus, and basic system commands
fluently before attempting
to program the system. In case a user is selecting projects to
automate, he/she must be
sure that there is enough work to offset both training costs and
software development
costs, especially if extensive programming is required.
It is recommended to first
automate tasks which will save the largest amounts of money
and which have the best
probability of successful completion on the system. Remember
that no work will be done
if assignments are beyond the abilities of the operators.
Schedules must include
time for system development or capabilities will level off
quickly. Development
should be applied to areas that will most benefit the bulk of group
responsibilities. All
members of the CAD team should participate in analysing work in
order to find "the
better way to do it" on the CAD system.
The CAD manager must be
versatile enough to make CAD work in the department and to
direct its evolution
within the company.
Written procedures are
important because they provide clear, indisputable instructions to
CAD personnel and CAD
users know what is expected of them in specific terms. If users
become confused concerning
task requirements, they can communicate their complaints
more clearly by referring
to parts of the procedure that need embellishment or revision.
Procedures should be
updated as needed to simplify and streamline operations, and
provide the best
integration with other departments using the CAD database.
Procedures are also
valuable because once they are finalised they can be reused. They
help train new users and
refresh casual users, and information is not lost when key people
leave the company. Good
procedures will provide a sound basis for productive CAD
development in the
company.
