CAD-Computer Aided Design :: Computer Science

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 â€Å"Grading.† Grading is mathematical and involves working out smaller measurements, having to make each pattern piece bigger or smaller. Computers are used to do this because it makes the process much quicker and accurate Cad has a number of advantages -Data from pattern-making programs can be used to instruct machines to cut pieces out from lengths of fabric -Drawings or designs can be scanned into the computer and a wide range of repeat patterns and colour options generated in minutes. -The finished fabrics can be chosen from the screen by a client or customer and then printed using a digital printer. This is a big advantage for companies or industries using a one-off production, where they are making a garment to meet the standards and desirable needs of one particular customer. Them being able to choose their desired fabric/material is an advantage for the company as they are making something the customer chose themselves. -Changes can be made quickly as a customer waits. -Designs can be stored at a late date is then changed -Images can be sent electronically, directly to the client to view and have their opinions towards it. Disadvantages -There is an initial training period before the software can be used. -The software is also expensive. Therefore, other clients or factories may not have the same software. -If there is a problem with the computers, then all the work Is on hold, until an engineer is present to fix the problem. CAD helps speed up the entire design, manufacturing and retail process. The more new styles mean more sales are generated. Some stores want a new garment produced for them every month to maximise variety.
