Computer aided design, better known as CAD, deals with a huge range of computer related tools and applications. These tools are designed to be helpful to architects, computer and design professionals in their respective work and activities. Nowadays business organizations offering services like 2D drafting, 3D modeling, and solid design modelers have started using CAD as their fundamental system. The whole process of designing with the help of CAD includes both software and sometimes specially created hardware.
Drafting is a specialized skill that involves preparing technical drawings and plans, which are used in the fields of architecture, industrial design and plant design. Today, with companies preferring to concentrate on their core business, the business of computer-aided drafting services is booming. Especially in the West, companies prefer to outsource drafting services to other countries like India, taking advantage of the lower costs. The result has been a boom in outsourcing.
There are many specialties in drafting services. These include aeronautical, architectural, civil, electrical, electronics, mechanical, and other types of drafting services. Electronic drafting may involve wiring diagrams, circuit board assembly diagrams, layout drawings, schematic diagrams used to manufacture, install and repair electronic devices etc. Architectural drafting may involve cross-sectional plans, elevations roof framing and foundation plans, reflected ceiling plans, raster to vector conversion, survey-based site plans and landscape plans, interior plans, 3D views of residential and multi-stored houses, 3D walkthroughs etc.
As we mentioned earlier, almost all this kind of work is done through computer-aided design and drafting (CADD systems). These allow drafters to create and store drawings electronically so that they can be viewed, printed, or programmed directly into automated manufacturing systems. CADD has brought about huge efficiencies and reduced costs for companies. Earlier, when there was a change in plans, drafters had to draw all over again. Today, CADD enables changes in a matter of minutes.
In short, with the increasing usage of computers, CAD began to be used extensively for construction related work and activities. CAD, which started with 2D services, went on and on. Now there are a range of CAD based products available in the market.
