PURPOSE AND RATIONALE OF THE QUALIFICATION
Any learners, who are, or wish to be involved in the Computer Aided Drawing, will
have access to this qualification. This qualification is intended to serve the
architectural, engineering and construction industries by providing skilled
draughtspersons who can produce design drawings which address the need to
move from traditional manual drafting to Computer Aided Drawing and Draughting.
Portability across other National Qualifications in Engineering and Draughting is
The qualifying learner will be capable of:
ï?· Understanding the Computer Aided Drawing office environment.
ï?· Using Computer Aided Drawing office equipment and instruments.
ï?· Producing Computer Aided drawings.
Computer Aided Design supports the Design Engineering activity that includes
creation of 2D/3D Geometric models doing engineering analysis, evaluating the
design by simulation and produce rapid drafting for manufacturing with the help of
computers. The traditional CAD System offers 2D drafting, 3D modelling with
limited modification capability. This system substitutes the drafting board
completely. The high end 3D CAD tool provides many solutions under one
platform. If alteration is made in one feature then it will automatically change other
related (dependent) features. Dimensional and geometrical constrains play a
major role in this parametric design technology. Testing the designs on the
computer instead of expensive and time-consuming field tests leads to significant
reduction in product development cycles. Cost and time to market is another
advantage. The modern CAD System helps product design under practical
constraints helps enormously imaginative concepts.
