楼上说得好，但这可能确实是pcdmis的一个bug吧，他这软件你了解得多了，你就会觉得好多问题，但这软件还贵得要死，不要气愤，这社会就是这样的，呵呵 楼下是我搞的一个东东，是参照10楼的思路搞出来的，貌似问题已经解决，多谢yj407和各位热心的友友支持，哈哈！！！

:O 海的高手呢？技术专家呢？软件工程师呢？谁来解答下这个问题？:D PC-DMIS是界定内部 or 外部程序的原则是什么？标准是什么？ 我个人蛮赞同20#的看法:)

几年前我也发现这个问题。从使用者的角度来说软件有BUG也好或者设计者有其他用意也罢。用户使用只要能正确达到目的就行。 就算有BUG，只要发现了就得用其他途径来弥补。 当时是把测量部分放前面，CASE部分放测量程序后。程序能正常运行。 [url]http://bbs.hexagonmetrology.com.cn/showtopic-6938-5.aspx[/url] 这个程序里面应该就有这部分。 还有用变量也可以达到目的。
