This paper researches laying out mode and procedure of manual drawing , describs in bfn constructing elements and their structure of working drawing , and determines factors which affect drawing effect . it introduces simply that functions of an interactive drawing software , which are basic and special laying out characters , methods of modification and logical order of normal drawing . also an example is given . the paper formulates out a helpful method with which engineering drawing is drawed under interactive system 研究了传统绘图模式的构图方式和过程，用巴科斯范式描述了零件图的构图元素与结构，确定了影响绘图效率的因素.文中简要介绍了交互图形软件具有的基本的和特有的功能，在交互绘图中的构图特点，图形的生成与修改，一般作图的逻辑顺序，同时给出了示例.该文归纳出用交互图形系统生成工程图样的便捷方法
Solidness , which indicates that solid objects in the real world do not pass through each other when they collide , contributes to improve realism . enforcing this property is important in interactive graphics applications , especially large - scale virtual world with high demand on realism ; as a result , collision - detection is necessary “不可穿透性” ，即交互图形系统，尤其是虚拟世界应用中的物体，若发生碰撞，不能毫发无损地穿透彼此，是真实性的一个重要的体现和要素，因此，碰撞检测十分重要。
