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

希望大神指点

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

C:\Users\99112\Desktop

[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

* ~1 e8 _% L1 t
, ~7 S( x3 ~2 @[mw_shl_code=cpp,true]        Features::Feature *feat1;
        feat1 = divideCurveBuilder1->CommitFeature();[/mw_shl_code]
* E. c( c" E8 l1 T) i" d1 m! i! z) \代替
[mw_shl_code=cpp,true]    NXObject *nXObject1;
2 y0 Z1 k8 z! s3 c# B6 s: i9 F; Y$ o    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？？
