Lisp修剪简单图案填充
很好的一天！我在做一个例行公事
1.输入矩形大小>>完成
2.插入自定义图案填充>>完成
3.修剪边界，使填充图案成为四边形Polyn（如图所示）>>需要帮助
4.PEDIT>>我能应付
5.挤出>>我能处理
我需要第三位的帮助。矩形不同，图案填充也不同。但基本上，它通常是在附加的图像。

有可能吗？非常感谢。 首先分解图案填充和关联边界。。。
然后
这里是否解释了这些程序：
http://forums.augi.com/showthread.php?168170-连接处修剪需要Lisp&p=#2
创建复杂区域后，分解它并使用JOIN命令将轮廓转换为LWDOLYLINE，或根据需要进行PEDIT（多->连接）选项。。。
HTH。，M、 R。 谢谢marko，但我只有autocad 2007。我在看那些应用程序，total boundary pro似乎可以即时处理这些应用程序，但根据他们的网站，autocad 2007不支持这些应用程序。我会详细调查的。 我做了一些类似的事情，诚实地说，从来没有真正完成它，但它在任何形状内绘制平行线，而不是图案填充，它没有连接两端，因为它使用extrim来剪裁比形状大的线。

下面的代码来自李·麦克。我在另一个网站上看到的。我把它贴在这里可以吗？归功于李·麦克。

我所做的是修改了他的代码以打断所有相交的线。
我现在的问题是如何选择具有特定层且长度不超过1英寸或1个单位的所有行。我对autolisp有点陌生。我只在网上查看代码并修改试错，但我不知道如何按层和长度筛选行。
（ssget“_X”'（（0。“LINE”））
或者这也起作用了
（ssget“_X”'（（8。“layername”））但我需要指定关于特定长度的条件。
如果有人能帮忙，谢谢 谢谢，我会调查的。
