标题: UG/KF中trim_body命令怎么用？帮我看看这个谢谢了
在裁减体的时候遇到了困难。我的dfa文件如附件一，对应的图如附件二。现在就是要用trim_body命令裁减掉两个圆锥面上面部分。我在建模环境下先裁减掉，然后用KF的"几何采用"命令。手工裁减后的图如附件三，几何采用后的trim_body子规则的编辑状态如附件四。在这个子规则编辑对话框中，Target（list）这一项的规则值为空，即{}。那么怎么才能编程实现这个trim呢？也就是该怎么解决这个Target规则值呢？谢谢了。真的很急，我是试了很多次，没有试出来。

我的dfa文档如下，该在这个文档下怎么加一个trim_body命令才能裁减掉呢？十分感谢各位热心人了。

你提到过的下面这段程序

不完整，请补全。

作者: lnw430522 时间: 2007-10-6 09:19
就是ug_trim_body这个命令不会用，也不知道怎么补全？谢谢魏师兄了。对于ug_trim_body这个命令中的target选项有什么具体要求呢》？谢谢了

作者: herryweiwei 时间: 2007-10-7 01:08
从语句上看，ug_trim_body命令的用法没有错误，所以要求你给出整个程序，怀疑是其他的地方定义有错误。你在此贴中所给出的三个文件中没有ug_trim_body命令，是在另一个文件中的，你在qq中发给我的也不全请给全。

注：钻体程序生成的图如上面的第一个图，这就是整个程序。现在要解决的问题就是在第一个图的基础上进行裁减，不知道怎么用ug_trim_body这个命令进行裁减？谢谢魏师兄了

对不起，最近有点事，没能给你解答问题。我现在想要的就是你将这3个文件串起来的、相互调用的那个dfa文件，你在qq上发给过我，但不全。你提到不知道怎么用ug_trim_body这个命令，但是你上面提到的程序中没有ug_trim_body这个命令。其实它的用法很简单，你可以参考清华的那本kf的书，也可以看帮助文档，而且就我看你的语法是没错的。可能就是那个用到ug_trim_body的dfa文件在定义大类、子类的时候有问题（注意：调用的时候也分大类子类依顺序写），你可以查一下。

程序改成如下，应该就可以了。因为没用ug调试，如若不行，但思路应该没问题。
