The paper introduces the way of solid modeling and wire frame modeling, described modeling ways from drawing the general outline of the form, to using the general model to make out the general modeling of form, to making the whole effect of the animation by combining with concrete examples which are pf rapid and convenient application value in promoting design speed, enriching expression effect (surface modeling), optimizing design process. It is beneficial to play the design wisdom, give consideration to both economic and social benefits. Its modeling is easy to meet consumer demand for fresh and exaggerated things, and helps to clear the market demand, good commodity modeling and its industrialization prospect.

Starting from constitution of design symbols, this article analyzes the constitution forms before sending and receiving messages, the decomposed information carriers of senders and receivers, the coding rules of sending messages formulated by senders and decoding rules of receiving messages by receivers, thus concludes three basic rules, namely, regular、irregular and mixed type of understanding.
