阐述了在开发ＣＡＤ／ＣＡＭ系统人机接口时对话结构生成器的原理，它是基于单－交互原语和多类菜单的结构上。概述了新型图型系统设计、描述和实现方法。它的实现，解放了接口设计者的工作，体现了当代软件工具和环境的新思想．
The principle of the conversation structure generator when developing the human-machine interface of CAD / CAM system is expounded. It is based on the structure of single-interaction primitive and multi-type menu. An overview of the design, description and implementation of a new type of graphics system is given. Its implementation frees the interface designer’s work and embodies the new ideas of contemporary software tools and environments.
