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();
. R5 D3 l2 |3 u2 m, V. h                Part *workPart(theSession->arts()->Work());
: V* f3 G8 b/ h1 B$ F                Part *displayPart(theSession->arts()->Display());

0 c4 ?  c' H0 D" c7 L2 @                std::vector<TaggedObject*>pp = point0->GetSelectedObjects();    //获取选择的点
                TaggedObject * p = pp[0];
                Point * getpoint = dynamic_cast<oint*>(p);
