With the rapid development of computer-aided design, traditional hand-drawn performance undergoes a fundamental change. Since it has the characteristics of a variety of vivid, fast and convenient, the computer-aided design has become a new desinging trend. However, while the computer brings us conveniences, it also has many negative effects. Many designers rely on the computer-aided design excessively, and ignore the hand-drawn performance’s special advantages of enlightenning creative thinking, emphasizing the personality performance, promoting computer performances, and improving professional attainment. In the informationlized computer age, in order to better reflect the design’s essential connotation, we only have to combine the hand-drawn performance and the computer-aided design together perfectly, and coordinated development of the two should be the orientation of contemporary design.
