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：
/ f+ L; ?6 }0 S            //两点创建直线
  C3 M* f7 M  y  L5 p           
                Session *theSession = Session::GetSession();
- B' n' k& @5 Z0 G/ J% l/ o                Part *workPart(theSession->arts()->Work());
                Part *displayPart(theSession->arts()->Display());

( Q8 V6 g: f6 H' ~                std::vector<TaggedObject*>pp = point0->GetSelectedObjects();    //获取选择的点
" M0 i$ x9 `8 O. F, z                TaggedObject * p = pp[0];
                Point * getpoint = dynamic_cast<oint*>(p);

2 ?6 p0 O% q  S1 S5 d2 v
                std::vector<TaggedObject*>qq = point1->GetSelectedObjects();    //获取选择的点
                TaggedObject * p1 = qq[0];
                Point * getpoint1 = dynamic_cast<oint*>(p1);
