迭代坐标系的移动隔离区

若使用有迭代坐标系的排外区（插入 | 移动 | 排外区），PC-DMIS 自动计算要重新执行之测量例程的起始和终止行。这就意味着PC-DMIS将会吧执行的最后一个特征作为迭代法建立坐标系的一部分。如此可防止一条臂释放排外区给另一条臂，由此而停止测量例程。

为了解决上述情况，为迭代法坐标系插入一个开始标号。PC-DMIS在迭代坐标系之前从标签执行到命令，这导致臂释放排外区。

已停止的测量例程的示例：

在下面的程序中，PNT3赋值给二臂，其余指令均赋值给一臂。

注解：即使点PNT2位于PNT1和PNT2之后并且在CIR1和CIR2之前，决定于PC-DMIS的内部逻辑以及隔离区域的存在，PC-DMIS将会在PNT3之前测量PNT1，PNT2，CIR1和CIR2。因此，在CIR2之后的隔离区将不会开放而且会阻止二臂测量PNT3。

如果你在你坐标系特征的开始使用起始标号然后用此标号屏蔽你迭代法坐标系指令的运行，你将会遇到如下问题，像这样：
