Abstract
In the systematic engineering of product, the use of personal computers as practical 'hands-on' tools for designing should increase. personal computers can be used effectively for many functions, 3D renderings and animations. variations of idea sketches and so on. However, the complexity of 3D plastic modeling and the linkage with drawing programs are still awkward. There is a possibility that if we become reliant on the computer to develop the designs, we may risk only producing the products which are easier to design on the computer. How an object and feels to the touch and affects our five senses are the last and still the most important aspects in the consideration of a design.
