结合中遇到的问题

请问怎么把NXOPEN创建的直线用UF的函数生成管道呢。我在界面上能获取任意两点生成直线（nxopen实现的），把直线转换成UF函数里边的参数后管道不能创建，请求帮助，代码如下：
            //两点创建直线
           
                Session *theSession = Session::GetSession();
                Part *workPart(theSession->arts()->Work());

                std::vector<TaggedObject*>pp = point0->GetSelectedObjects();    //获取选择的点
) r% _% \9 c) }( ^9 ]                TaggedObject * p = pp[0];
