can any one tell about drafting?

Answer 1

Drafting, or slipstreaming, is a technique in sports racing where competitors align in a close group in order to reduce the overall effect of drag or fluid resistance of the group. Especially when high speeds are involved, drafting can significantly reduce the average energy expenditure required to maintain a certain speed.

Drafting is usually to reduce wind resistance and is seen most commonly in bicycle racing, car racing, and speedskating though is occasionally used even in running. Some forms of triathlon allow drafting. Fluid resistance can also mean water resistance, however, and so drafting is sometimes seen in swimming as well, particularly in "open-water" swim events where competitors are not separated into distinct lanes.

In cycling, the main (largest) group of tightly packed cyclists in a race is called a peloton, while cyclists riding in straight-line formation, each (but the first) drafting behind the one in front of him, is called a paceline. Drafting can be cooperative, in which several competitors take turns in the lead position (which requires the most effort and energy consumption). Or, it can be competitive or tactical, where one competitor will try to stay closely behind another leaving him or her more energy for a break-away push to the finish line

Significant Points

The type and quality of postsecondary drafting programs vary considerably; prospective students should be careful in selecting a program.
Employment is projected to grow more slowly than average.
Opportunities should be best for individuals with at least 2 years of postsecondary training in drafting and considerable skill and experience using computer-aided design and drafting (CADD) systems.
Demand for drafters varies by specialty and depends on the needs of local industry, particularly architectural and engineering services and manufacturing.


Nature of the Work [About this section] Back to Top

Drafters prepare technical drawings and plans used by production and construction workers to build everything from manufactured products such as toys, toasters, industrial machinery, and spacecraft to structures such as houses, office buildings, and oil and gas pipelines. Drafters’ drawings provide visual guidelines; show the technical details of the products and structures; and specify dimensions, materials, and procedures. Drafters fill in technical details using drawings, rough sketches, specifications, codes, and calculations previously made by engineers, surveyors, architects, or scientists. For example, drafters use their knowledge of standardized building techniques to draw in the details of a structure. Some use their knowledge of engineering and manufacturing theory and standards to draw the parts of a machine to determine design elements, such as the numbers and kinds of fasteners needed to assemble the machine. Drafters use technical handbooks, tables, calculators, and computers to complete their work.

Traditionally, drafters sat at drawing boards and used pencils, pens, compasses, protractors, triangles, and other drafting devices to prepare a drawing manually. Most drafters now use CADD systems to prepare drawings. Consequently, some drafters may be referred to as CADD operators. CADD systems employ computers to create and store drawings electronically that can then be viewed, printed, or programmed directly into automated manufacturing systems. These systems also permit drafters to quickly prepare variations of a design. Although drafters use CADD extensively, it is only a tool. Persons who produce technical drawings with CADD still function as drafters and need the knowledge of traditional drafters, in addition to CADD skills. Despite the nearly universal use of CADD systems, manual drafting and sketching still are used in certain applications.

Drafting work has many specialties, and titles may denote a particular discipline of design or drafting.

Answer 2

Litral meaning if drafting is composing some leter, map or text. But in general terms drafting is drafting of Maps used by Architects and Land records. A draftman is a person who is required in various departments and organisations. A one/two year ITI diploma courses are run by different government Institutes.

Answer 3

Did you mean CADD (Computer Drafting) Or Architectural drafting? I used to be an interior Design major, so I had to take architectural drafting classes, which I thought was time-consuming but challenging. I wasn't as good at it as some of my friends were, but I switched majors and that's another story :) Good luck

Answer 4

If WMD went off on US soil, there does no longer be a want for the draft. i understand a brilliant style of the U. S. might upward thrust up and take palms against the undesirable bastards that dared to attack us. recover from your self. do no longer connect the protection stress. they do no longer want you.
