Abstract

3D modeling method is one of the most important techniques in product design with computer-aided design systems. The methods for 3D modeling which are used in different kinds of CAD systems are nearly the same in principle. Due to the constraints that are often exerted to the users we can hardly construct complicated 3D objects. A new concept for 3D modeling called folding is proposed in this paper. With the principle of the new concept we could develop advanced 3D modeling method in CAD systems. It is a key point of this paper that a 2D graphics is folded into a 3D solid.
