Revit—CableTray and Conduit 桥架线管打断

承接上两篇文章的讨论

第一篇：Revit—线管连接桥架

第二篇：Revit—Duct打断和Pipe打断

这篇文章讲一下实现桥架线管打断的思路，并提供可用方法代码

打断管线并不复杂，复杂的是要恢复原有管线的连接。桥架和线管有和水管不一样的特点，上面第一篇文章写了，它能连接成你“意想不到”的样子，要恢复这种连接，也就存在一些技巧了。

另外，根据文章二提到的Revit自带的两种管线打断方法测试可知，打断操作是保留原始管修改迹线，然后创建一个新的管补充到另外的区域。

保留哪部分区域？这里面就会涉及一个策略问题。我下面的方法的策略是，尽量保留连接多或者复杂的一端，创建连接少或简单的一端。

直接上代码了，考出去就能用的那种(#^.^#)
