NXOPEN C++: Features::TubeBuilder从Block UI获取路径pathsection()​的问题？

Question

//从Block UI（截面构建器）获取曲线，赋值给vector 类型变量tagObjArray

NXOpen::BlockStyler::PropertyList* SectionToTubeproplist = SectionToTube->GetProperties();
std::vectortagObjArray = SectionToTubeproplist->GetTaggedObjectVector("SelectedObjects");

NXOpen::Features::Feature* nullFeatures_Feature = NULL;
NXOpen::Features::TubeBuilder* tubeBuilder1 = workPart->Features()->CreateTubeBuilder（nullFeatures_Feature);

//定义管道路径

tubeBuilder1->PathSection()->AddToSection();

到这一步需要如何把tagObjArray对应的曲线转成管道路径？

求大神指导！

谢谢。
