用单个视图表达物体的一种方法

One way to express a single view of the object

断面相同或相近的物体,在表达断面形状的视图上,标注附加投影方向的尺寸,可以在一个视图上同时反映物体长、宽、高三个方向的尺寸,从而实现用一个视图表达物体的形状。对于断面相同且被截切的物体,所表达物体的形状与尺寸标注的位置有关。

On the view for expressing cross-section of objects with same or similar cross-sections, it can be achieved that one object can be expressed fully by only one view with additional dimensions from projection direction, forming dimensions from three directions--length, width and high on one view. The shapes of objects to be expressd are related to the vositions of dimensions.
