Today, Computer Aided Design (CAD) is utilized in a variety of fields. Engineers, architects, and industrialists have incorporated CAD into complex designs for more efficiency and to save time. Traditionally, designers used drafting machines (drawing tables), which took a long time to produce blueprints. For example, if a designer made a mistake on the drawing table, he/she would have to start from the beginning.
When using CAD software, a mistake can be undone with a click on the keyboard. When you see a new gadget being marketed in the media, it most likely has a blueprint that was created using CAD software. In contrast to the traditional way of creating blueprints, CAD streamlined this process to deliver the new gadget to the end-user in a much quicker time frame.
