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
) v- k- r* v/ Z           
                Session *theSession = Session::GetSession();
* [1 U' p, m, R                Part *workPart(theSession->arts()->Work());
  _2 t5 B. k* ~* Y# |" p0 B                Part *displayPart(theSession->arts()->Display());

                std::vector<TaggedObject*>pp = point0->GetSelectedObjects();    //获取选择的点
' @9 n! L( f4 i                TaggedObject * p = pp[0];
                Point * getpoint = dynamic_cast<oint*>(p);

% n" F. V2 W7 t2 E% X
                std::vector<TaggedObject*>qq = point1->GetSelectedObjects();    //获取选择的点
                TaggedObject * p1 = qq[0];
