explain the use of CAD systems to produce engineering drawings

CAD(Computer Aided Design) is the use of computer technology for the design of objects, real or virtual. CAD often involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD often must convey also symbolic information such as materials, processes, dimensions, and tolerances, according to application-specific conventions.

CAD may be used to design curves and figures in two-dimensional (“2D”) space; or curves, surfaces, or solids in three-dimensional (“3D”) objects.

CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by shipbuilders of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.


interpret drawings,dimensioning and labeling

describe how to use charts ,tables ,graphs and BS EN standards

describe how to extract information from drawings

describe how the use of engineering drawings to determine quality requirements.


For above point u have to learn cad software…… its bacis commands of autocad
