RationalDMIS 2020 自学习编程详解
通过矢量点坐标，矢量方向的名义值去测量点。
点元素用于定义工件上每一个点的X、Y、Z坐标值，可在平面或曲面的任何位置测量，测量结果可输出每个点的X、Y、Z坐标值和测量点在探测方向上实测点与理论点的距离，常用于工件上某位置或特征的测量。
在产品的加工过程中，为了保证加工精度，加工余量通常是重点关注的问题。模具类产品加工具有加工时间长、工序环节多和使用刀具多等特点，加工余量的控制在模具加工中显得尤为重要。
“点元素测量”功能支持在产品面上快速布置测量点，并生成相应DMIS程序，实现产品的中间过程加工余量检测和成品的最终检测。测量结果可在图形报告区生成直观的图形报告测点报告，通过图表科学可靠的分析产品余量分布情况，帮助工艺人员改进工艺方案。同时对复杂图形及其它检测方式不支持的特征，也可使用“批量点测量”进行相关位置误差的检测。
1）导入模型
2）建立与模型坐标系相同的工件坐标系后，模型对齐。
3)CAD点型图形定义：拾取点
直接在模型上用鼠标左键拾取要测量的位置
4）批量测量点
将所测量的元素全部选中，拖放到DMIS区“拖放到测量块”图标。
从MODE/PROG,MAN（模式/程序模式，手动模式）处开始运行，运行一遍所产生的元素的DMIS程序。
注解：当使用PROG模式时，测量设备会按照下面所给的PAMEAS、PTMEAS和GOTO语句去测量元素。
附注：
另外2种方法如下
1.元素右键“自动测量”
2.MEAS DMIS
打开自学习的情况下，自动生成一段测量该元素的DMIS程序。
3.点组功能
程序设置一点元素DMIS测量语句组
当设置为是，多选点元素标签拖放到DMIS程序区弹出菜单一个选项来创建点群测量块。
MEAS/POINT方式DMIS编译器会等待ENDMES直到测量完成。MEAS/GROUP会先将多个点测量完再来计算成元素，所以会提高运行效率；
