pc里的多重目标是不是只能在做分离式路基时使用？

Hi，

感觉你的英文应该还不错。从帮助文档里截出一些话，完全能回答你的问题：
第一段说的是TargetAliasing的功能，到底能处理什么问题。
Target aliasing allows you to target other corridor surfaces or features or to set up a prioritized target list for end condition solutions on surfaces, features and alignments. This means that on a large job where the existing surface may have been broken up into more than one surface, you don’t need to be concerned about where those breaks occur, and you don’t need to create a different template for each existing surface. Use target aliasing to find the proper solution.
第二段说的是TargetAliasing与PointControl的关系。
Target Aliasing can not be defined with a corridor that targets that particular corridor with a Corridor Point Control. This produces a recursive situation, making the corridor unavailable for Target Aliasing until that corridor point control is removed.

看起来是不能用了。
其实civil3d里面在做交叉口设计的时候。可以赋予多重逻辑目标。希望你们能加入这个功能。
多谢~
