CAD – A Revolution for Engineering Drawings and Designs
CAD is the abbreviation of "Computer Aided Design". It is a structure of design in which people work with computer tools for creating models, drawings and other prototypes. CAD was first developed in 1970s with 2D in order to assist engineers, architects, and other design professionals in their technical drawings and drafting, but now it has expanded with numerous other potential uses with 3D designs and models. Designers from various fields such as Engineering, Architecture, Fashion, Textile and Graphics are highly dependent on CAD technologies. CAD is considered as a revolutionary design tool, which provides cost-effective solutions with quick time interval.
The entire process of design using CAD involves both software and sometimes specially created hardware related to a specific industry or application. Latest systems like 2D drafting, 3D modeling and solid design modelers use CAD for their fundamental operations. Manufacturers use CAD to design virtual products, which can be tested and measured for performance. Without CAD, the entire process of manufacturing a product and then testing would be very expensive.
Computer Aided Design (CAD) is a derived technology of Co-ordinate Geometry, which is a branch of Mathematics. Due to this reason the basic entities used in any CAD environment are points, lines, polygons, texts and other geometrical figures. These entities have been further modified to create circle, ellipse, parabola, hyperbola, mesh and also three dimensional (3D) objects like spheres, cubes, cylinders and many more. Further developments have been made according to the design requirements.
CAD is a computer-assisted technology, basically used for creating graphics designs of various objects or goods considering about its consumers. It is most extensively used in the design and development of machinery. CAD is also used widely for the designing of all types of buildings. Engineering industries use CAD right from the product conceptualization stage across the entire process of manufacturing.
Now days Computer Aided Design (CAD) is used in many technical or engineering fields like architecture, civil, mechanical, aviation, ship building, construction, electronic, electrical and automotive. Architects and civil engineers use CAD to design buildings structures and interiors. In mechanical engineering, CAD is used for 2D cad drafting, legacy data conversion, data migration, platform migration, mechanical 3D modeling, solid modeling, sectional drawing preparation and isometric presentation. Electrical and electronics industries use CAD for making Printed Circuit Board (PCB) designs and wiring layout (WL) designs. CAD is also used to design the generally layout of a manufacturing unit.
3D modeling and surface construction methods are used especially in mechanical, aircraft and automotive industries to design different products and components for machinery. The entire process not only saves time and money but also guarantees optimum accuracy and correctness. After complication of CAD design the results are directly inserted into the manufacturing process using Computer Aided Manufacturing (CAM) systems in many modern sophisticated industries. Various industries use CAD for different design purposes according to their requirement. The aerospace industry was the first to use CAD commercially and popularize it as a designing tool.
Extensive use of computers in day to day life facilitates the use of Computer Aided Designs in the field of engineering and has created a revolution in industrial sectors. Due to its immense application in industries CAD has got emphasized, more and more CAD based products available in market.
CAD has revolutionized the complete engineering developments. CAD engineering enables us to see more and more new products in the market everyday. Computer Aided Design engineering is also responsible for the initiation of robotics into the manufacturing sector for enhancing industry production.
