识图技能 第一节、工程识图 1、体的投影 体的投影，实质上构成该体的所有面的投影总和。运用点、线、面投影规律，就可以分析体的投影（如下图1-1）。 平面ABCD和平面EFGH都是水平面，平面AEFB和DHGC都是正垂面，这四个正面投影都积聚成直线。前后两个平面BFGC和AEHD分别为侧垂面和正平面，其正面投影重合线框b’f’g’c’(a’e’h’d’)。在水平投影中abcd和efgh反映实形，abfe,dcgh和bfgc具有类似性，aehd则积聚为一直线。 图1-1：体的三面投影 图1-2：体的三视图 2、投影与三视图 视图：就是将产品向投影面投影所得的图形。 投影面上的投影与视图，在本质上是相同的。工件在三个基本投影面上所得的三视图分别称为： 主视图：由前向后投影，在V面上所得的视图。如图1-1所示 俯视图：由上向下投影，在H面上所得的视图。如图1-1所示 左视图：由左向右投影，在W面上所得的视图。如图1-1所示 三投影面展开后，平面体的三视图如图B所示。 根据投影分析，三视图之间有两个重要的对应关系，即： 之间的度量对应关系 图2-1：体的三视图
