(CAD) Computer-Aided Design
Computer-Aided Design (CAD) is a computer technology used to design objects,real or virtual. CAD may be used to design curves and figures in two-dimensional ("2") space, curves, surfaces, and solids in three- dimensional ("3") objects.

Computer-Aided Design is one of many tools used by engineers and designers and is used in many ways.

CAD Software will let you:

• Switch between two-dimensional ("2D") and three-dimensional ("3") views
• Zoom in and out for close-up and distance views.
• Rotate images for different perspectives.
• Change the scale of images: value changes automatically adjust.
• Manipulate the shape of images: When one portion is changed of an image, it automatically changes the entire picture.

This Software is used by engineers,architects and designers. But it is now available on personal computers for users to work in the comfort of their homes. It is creative and has a lower product development cost.

Nowadays educational institutions are looking forward to teaching CAD to their students so that they can be aware of the most modern technical advancement in the field of designing.

I believe that both teachers and students can benefit from this software because you can use a computer program rather than pen and paper. It saves time and takes only minutes to make changes if there are any. And you can even create 3D design and visualize exactly what it is. It is fun and easy to use and saves you a lot of money.
