摘　　要：使用UML技术,采用核心→边缘、主干→细化的螺旋式功能设计方式,使得所设计的曲面造型系统的各种功能拥有比较清晰的层次性。同时,在系统内核的设计上使用了插件和双显示链表的思想,从而保证了所设计的曲面造型系统拥有相对灵活的可扩充性和及时的设计反馈速度。所有这一切都为随后的程序实现奠定了坚实的基础。UML technology-based augertype functional design method of ＂core to edge＂ and ＂think to refined＂ was adopted to make every function of the surface modeling system a comparatively well-defined arrangement. At the same time, the idea of insertion piece and dual display chain table was used in the design of system kernel, which would guarantee the surface modeling system a flexible expandability and opportune design feedback speed. All of this would establish a solid basis for the implementation of next step program.
