Functions in Aiding Design

Abstract

In the initial stages of designing a product, there will be various requirement regarding the product’s appearance, quality, reliability, or cost. Often, it is difficult to satisfy all these requirements completely. Conventional CAD systems enable designers to model the required geometric shape, although this does not always meet with the desired requirements. If it does not, the shape has to be corrected. In addition, the changing requirements of a product means that the product shape has also to be modified sometimes. Because of this, the functions that easily modify the product shape once it is designed are indispensable to design flexibility and productivity. In conventional CAD systems, however, functions that aid design have not been fully supported, thus making the modification in product shape very difficult.
