Dimensioning general composite solids 13 组合体的尺寸注法 2.Correctness and integrity in dimensioning标注尺寸要正确、 完整 (1)Shape dimensions show sizes,such as length,width and height,of the basic part and its building elements 点 定形尺寸表示洛基本体长、宽、高三个方向的大小尺寸 (2)Location dimensions show the relative location relationships between individual shape elements. 定位尺寸表示各基本体之间相对位置尺寸。 (3)Overall dimensions show the overall length,width and height of the composite solid. 总体尺付表示组合体外形的总长、总宽、总高尺寸 后 注意： 重要尺寸应直接注出（如总长、宽、高尺寸、孔的中心位置等），不应由其它尺寸计算求得。 不能注成封闭尺寸链，应选择允许误差最大处作开环。 R 容 Overall length added as an auxiliary Overall length must be given clearly (10) 长尺可寸应该直 接注出 13 (2) Location dimensions show the relative location relationships between individual shape elements. (3) Overall dimensions show the overall length, width and height of the composite solid. (1) Shape dimensions show sizes, such as length, width and height, of the basic part and its building elements. (10)
