CAD-Computer Aided Design Computer Aided Design systems make it easy to create a picture of a new design, then you are able to change the picture on the computer. This saves time because you don’t have to re draw everything from the way it was originally started of with. It is also quicker to evaluate. There are many different types of CAD programs available to the industries and designers. They are concerned with either the visual appearance of the product or the technical details and difficulties. Computers have become as integral part of the design. They can dramatically cut down on labour and time and also costs. Garments have to have production patterns made. From these you can then alter the sizes, shapes, styles etc The process of changing a pattern size is called “Grading.†Grading is mathematical and involves working out smaller measurements, having to make each pattern piece bigger or smaller.
