Computer Aided Design (CAD) is simply, design and drafting with the aid of a computer. Design is creating a real product from an idea. Drafting is the production of the drawings that are used to document a design. CAD can be used to create 2D or 3D computer models. A CAD drawing is a file that consists of numeric data in binary form that will be saved onto a disk.
Why should you use CAD?
Traditional drafting is repetitious and can be inaccurate. It may be faster to create a simple “rough” sketch by hand but larger more complex drawings with repetitive operations are drawn more efficiently using CAD.
Why use AutoCAD?
AutoCAD is a computer aided design software developed by Autodesk Inc. AutoCAD was first introduced in 1982. By the year 2000, it is estimated that there were over 4 million AutoCAD users worldwide. What this means to you is that many employers are in need of AutoCAD operators. In addition, learning AutoCAD will give you the basics for learning other CAD packages because many commands, terms and concepts are used universally.
