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();

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

捕获.PNG

[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

我用

[mw_shl_code=cpp,true] Features::Feature *feat1;
feat1 = divideCurveBuilder1->CommitFeature();[/mw_shl_code]
代替
[mw_shl_code=cpp,true] NXObject *nXObject1;
nXObject1 = cylinderBuilder1->Commit();[/mw_shl_code]
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？？
希望指点一下？
