CAD stands for Computer Aided Design which is a process of helping people draw, design and develop things with the help of specific computer hardware and software products. So, for example, an architect may use a CAD system to help him design houses or other buildings and a manufacturer may use it to design tools and machinery. Typical products in use here include options such as:

Nowadays a CAD system can allow a design to do much more than simply produce a technical drawing of a product or design. For example, you can use both 2D and 3D CAD packages which can allow you to rotate designs so they can be viewed from any angle. CADD (Computer Aided Design and Drafting) systems can also add mathematical modelling to the mix.

CAD systems can be used by any person in need of specific design technology. Common examples of CAD use include:

Using CAD allows companies to produce designs more efficiently and cost effectively as the systems mean that designs can be produced more quickly than they could by non computer based draftspeople.
