Abstract: The design method of special-shaped box is provided by applying
three-dimensional composition principle and treating papers as the objects, which make the design
rule of special-shaped box can be fined. The interactive design system of special-shaped box is
developed, and the function framework, design flow and the user interface of the system are
analyzed. At last, an example is used to show the system’s utility.

Key words: computer applications, design system, three-dimensional composition;
