但是出现了一个问题，在上述代码中，进行装配的面是通过FindObject来找到的，不是我想要的那个面，而且FindObject函数参数是一个JA标识符，我无法给某个面定义JA标示符。如果我在建立模型时，我给某个面命名为FACE1。那么我如何找到我想要的面FACE1，然后用于代码
% P1 q- m8 t: b: S# P; _

1. constraintReference1 = componentConstraint1->CreateConstraintReference(component2, face1, false, false, false);

复制代码

其中上述代码中第二参数类型是NXObject *，也无法通过Ufun函数的UF_OBJ_cycle_by_name找到，因为该函数找到是FACE1面的tag，返回的类型不是NXObject *。
问题:
  `! p: b) {" r6 X1)C++中是否有某个方法通过某个对象的tag返回其NXObject *类型
2）C++是否有某个类中的方法可以找到occurrence中的面（CreateConstraintReference需要的是occurrence的对象），而且返回的是NXObject *类型对象，可以直接用于CreateConstraintReference（）方法。

tag 可以通过 NXObjectManager 返回 NXobject
