Definition: Computer-aided design is the use of a wide range of computer based tools that assist engineers, architects, and other design professionals in their design activities.
Another definition for it would be the use of computer technology to aid in the design and particularly the drafting of a part or product, including entire buildings. It is both visual (or drawing) and symbol-based method of communication whose conventions are particular to a specific technical field.
CAD is translated into different names depending on the purpose it is used for. For example, "computer assisted" or "computer aided drafting" or even some related names are CADD which stands for "computer aided design and drafting". It all depends on the program that CAD is being used for.
What careers use CAD …?
Civil Engineering and Infrastructure
Electronic and Electrical
Manufacturing process planning
Digital Circuit Design
Apparel and Textile CAD
Designers have long used computers for their calculations. Initial developments were carried out in the 1960's within the aircraft and automotive industries. Most of it was independent of one another and often not publicly published until later.
American Ivan Sutherland invented CAD in 1961 when he described a computerized SKETCHPAD in a doctoral thesis while attending the Massachusetts Institute of Technology (MIT). He designed CAD to replace the traditional drafting board and other tools drafters used, such as the ink pen, plastic stencil, and electric eraser.
History Continued …
The first commercial applications of CAD were in large companies in the automotive and aerospace industries, as well as in the electronics. Only large corporations could afford the computers capable of performing the calculations.
As computers became more affordable, the application areas have gradually expanded. The development of CAD software for personal desk-top computers was the impetus for almost universal application in all areas of construction.
What are CAD’s advantages …?
3D detailed drawing
Computerized model to scale
Test without having to produce it
Drawings are device independent
You can resize easily by using calculation
More economical and efficient
Smaller files than bitmapped images
Easier to see the characteristics
Why is it better to use it …?
You basically draw on an electronic pad which transfers your sketch directly into the computer as a graphic file. It’s better to use CAD than to just scan designs into a computer because CAD produces vector art (points and lines) and not just raster pictures as with a scanner. The drawing pad which is an electronic drafting board combined with a pencil like object to create vector art from hand sketches on the pad.
How is CAD involved with Fashion …?
Computer-aided design (CAD) is increasingly being used in the fashion design industry. Although most designers initially sketch designs by hand, a growing number also translate these hand sketches to the computer. CAD allows designers to view designs of clothing on virtual models and in various colors and shapes, saving time by requiring fewer adjustments of prototypes and samples later.
