摘　　要：本文详细地介绍了一个具体的CAI创作系统《三维几何画板》的设计目标,它产生的背景、具备的各种功能、系统的组织架构和具体的内部对象的层次结构。分析了当前流行的类似系统的不足,以及本系统如何克服这种不足并形成为它们的一个有效补充。以丰富的图示说明了本系统颇具特色的属性定义机制。最后,介绍了本系统尚未解决的一些具体问题和今后努力的方向。In this paper, we have introduced the designing objective of a concrete CAI tool-the 3D Geometer＇s Sketchpad. And have also introduced the background of its arising, the various functions it owns, its infrastructure and the hierarchical structure of its interior objects. We have analyzed the deficiency of the current popular similar systems and pointed out how our system had overcome them, so to become an effective complement of the popular systems. We have introduced our special mechanism of defining operation of object＇s properties in detail. As a conclusion, we have pointed out some open problems of our system and the directions of our future work.
