Computer Aided Design supports the Design Engineering activity that includes the creation of 2D/3D Geometric models, doing engineering analysis, evaluating the design by simulation and producing 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 an alteration is made in one feature, then it will automatically change other related (dependent) features. Dimensional and geometrical constraints 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 a 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.

The FETC in Computer Aided Drawing (CAD) Office Practice is an entry-level qualification for the workplace designed in consultation with industry experts. Qualifying learners will gain a broad base of knowledge and skills needed for entry into the industry that will also provide the basis for further learning along this career pathway, including learners who:

• Were previously disadvantaged or were unable to complete their schooling and were therefore denied access to Further Education and Training.
• Have worked in Computer Aided Drawing for many years, but have no formal qualification in Computer Aided Drawing.
• Wish to extend their range of skills and knowledge of the industry so that they can become knowledgeable workers in Computer Aided Drawing and Draughting.
