CAA:求助 CATTransfoManager的参数的含义

我在做把立体给对称复制的命令
我开始用CATDynTransformation，为了能连颜色都一起复制，我用CATDynTransformation::CATDynModification模式，
但发现一个问题：如果复制对象里有孔之类的feature的时候，在3DView上点复制后的孔的面的时候，原来的孔的面也一起高亮（他们在同一个Body的时候）
于是我改用CATDynTransformation::CATDynCreation模式，并自己修改所有的面之间的CATCGMJournal为Modify，结果更坏，自己做的对称复制feature甚至不能高亮

后来改用CATTransfoManager，问题也没有解决，它的参数CATTransfoManagerType 的意思也看不太懂，不知道有没有用过它的同行能给指点一下
CATTransfoManagerType
enum CATTransfoManagerType {
  Duplicate,
  FullDuplicate,
  Replace
}

Defines the mode of the transformation process.
Parameters:
CATTransfoManager:uplicate
Duplicates and transforms the objects that are Added to the CATTransfoManager.
Does not duplicate a forward linked object if it is geometrically invariant by the transformation, except if this forward linked object is specifically Added to the CATTransfoManager. Duplicates a forward linked object if it is not geometrically invariant by the transformation.
CATTransfoManager::FullDuplicate
Duplicates and transforms the objects that are Added to the CATTransfoManager.
Duplicates a forward linked object even if it is geometrically invariant by the transformation,
CATTransfoManager::Replace
Only transforms the objects that are Added to the CATTransfoManager.
Does not replace a forward linked object if it is geometrically invariant by the transformation, except if this forward linked object is specifically Added to the CATTransfoManager. Replaces a forward linked object if it is not geometrically invariant by the transformation.
Invariant means that it is invariant within its maximum limits. An line is invariant by a transformation along its direction, a circle is invariant by a rotation of center the center of the circle, as examples.

求教怎么使用CATTransfoManager！！
