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

4 A! l$ v- X7 E, [* O  }    std::vector<NXObject *> objects1;
( _( @/ s- r8 J& R    objects1 = divideCurveBuilder1->GeTCommittedObjects();

2 G  \$ x  o; J

完整代码如下：

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。

另外一种方式就是生成的feature，通过feature去找对应的子对象

[mw_shl_code=cpp,true]objects1 = divideCurveBuilder1->GetCommittedObjects() [/mw_shl_code]的值一直是两个0，这段是录制jounal生成的，源代码就是这么获取的

7 f$ A9 D8 P6 W5 J. }我用

也可以分割一条曲线成两条   但是我想用这两条线怎么获取他们的tag？？
