NXOPEN创建组，并加入对象

Part *workPart(theSession->Parts()->Work());
 GroupBuilder* groupBuilder1 = workPart->CreateGatewayGroupBuilder(NULL);
    groupBuilder1->SetGroupName("123");//设置组的名字
groupBuilder1->SetGroupDisplayProperties(false);//设置应用组显示属性
    std::vector<TaggedObject *> objectsTag = selection0->GetSelectedObjects();//获取选择的对象
    NXOpen::Body *body = dynamic_cast<NXOpen::Body *>(NXOpen::NXObjectManager::Get(objectsTag[0]->Tag()));//tag_t转NXObject
    bool added1;
    added1 = groupBuilder1->ObjectsInGroup()->Add(body);
    groupBuilder1->Commit();
    groupBuilder1->Destroy();
