摘　　要：从投射方向、投影面旋转展开方法等投影基本原理这一层面上阐述剖视图配置及其相关问题。指出了剖视图可按基本视图的配置形式配置 ;也可按向视图的配置形式配置。文中提出 :当按基本视图的配置形式配置剖视图时 ,投射方向不需表示出来 ,即表示投射方向的箭头省略不画 ;当按向视图的配置形式配置剖视图时 ,投射方向必须表示出来 ,即必须用箭头指明投射方向。研究了国家标准 GB4 4 5 8.1- 1984第 4 .7款 。We studied the deployment of cutaway view and its relative problems on the lay of projective direction, projective plane rotating and development methods, pointed out that cutaway view can be deployed according to common view or direction view. We also pointed out that the projective direction need not be expressed, that is, the legend denoted projective direction can be omitted when deploy cutaway view according to common view, on the other hand, the projective direction must be expressed, that is, the legend must not be omitted when deploy cutaway view according to direction view. We also studied item 4.7 in the chinese national standard GB4458.1-1984, and some edit suggestions are given.
