应用最基本的标准几何元素建立工件坐标系。这种建立坐标系的方式既适合于接触式测量，也适合与影像测量。是最基本也是最常用的建立坐标系的方式。

用于建立坐标系的元素：支持所有类型元素

常用元素：平面，圆，圆柱，3d线，2d线，点（测量点和构造点）

3 空间旋转：第一基准轴或空转轴

坐标系建立的第一轴，决定了整个坐标系的方向。非常重要！

适用元素：“线”元素，如平面、圆柱、圆锥、3d直线

2 平面旋转：第二基准轴或者面转轴

用于确认旋转方向

适用元素：所有元素

“线”元素，如平面、圆柱、圆锥、3d直线

1 .原点

XYZ原点：确定坐标系原点的位置

需要三个元素分别确认X原点，Y原点，Z原点。

“点”元素，如点，圆，球，构造点（相交点，投影点，对称点等）

找正第 1 轴所选元素：

○线元素、面元素以及构造的线元素、面元素

找正第 2 轴所选元素：

○除了线元素、面元素，还可用点元素（点、圆、球等）,
以及由各种类型元素再构造的建轴元素。

如：一圆与一槽的连线、两圆中点与两圆中点的连线、圆与交点的连线等等诸多组合。

粗建坐标系不必一定建立在A、B、C基准上，而是应该建立在精加工面上，可以保证每次测量的稳定性。

零件坐标系建立在A、B、C基准上的好处是：在位置度，轮廓度评价时可以直接评价不需要拖放基准元素。
