PC DMIS RationalDMIS求最大(MX)最小(MN)函数
对于PC DMIS软件可以使用“表达式构造器”，对于点集可以构造特征组，赋值，最大，最小函数，进行评价！这种对于数量较多的很方便，也可以使用IF语句循环找最大值，最小值！
或者使用数组函数和最大最小函数配合，这个对于数量较少点实用性更强。

对于RationalDMIS软件，可以使用DO循环，一维数组变量对数据进行存储，使用最大(MX)最小(MN)函数求最大最小值。
软件官方提供简便的方法如下：
变量数据区自带了 找到最大最小点轮廓／直径／半径／XYZ坐标 的内置宏，可以帮助用户取得这些信息；
操作方法是拖放式，例如：
想取得PT1~10中最大最小点轮廓是哪个可以多选中这些元素丢到MINMAX_PROFP标签上；
