修改采样线名称

问题来源：

在Autodesk论坛中，一位朋友提出了这样一个问题：要把路线曲线点、超高点等特征信息在横断面图标题中显示出来，注意是横断面图。

解决方法：

如果直接解决这个问题，貌似不可行，但可以稍稍绕一点路，通过采样线名称来实现——把采样线名称当做横断面图的标题！

这样以来，我们只需修改采样线名称即可！手工修改应该不大现实，我们可以通过简单的代码来实现！

代码如下：

注意这只是测试代码，测试前提假定路线有一个采样线编组，如果采样线编组多于一个，代码也只能修改第一个采样线编组中采样线的名称。

超高点、纵断面点的操作类似，代码没有给出，有兴趣的朋友可以自行完成。

这些简写，可以通过修改图形设置进行自定义。
