NXopen C++ 分割成两段，我怎么得到两条线段的tag

SimonLv

我想请教一下大神：为什么我用分割曲线命令，将一条线分割成两段，我怎么得到两条线段的tag，这是录制代码，每到这里程序就蹦了

    std::vector<NXObject *> objects1;
    objects1 = divideCurveBuilder1->GeTCommittedObjects();

objects1 = divideCurveBuilder1->GetCommittedObjects()  这个是空吗？ 如果不是通常情况下，就是在这里，你可以打印看下。
3 W2 n' ?- p. b8 [5 y2 C# k. M3 N
另外一种方式就是生成的feature，通过feature去找对应的子对象
