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：
9 Q( ~: G# [" B7 G+ s: `. N; g            //两点创建直线

                std::vector<TaggedObject*>pp = point0->GetSelectedObjects();    //获取选择的点

                Point * getpoint = dynamic_cast<oint*>(p);

                std::vector<TaggedObject*>qq = point1->GetSelectedObjects();    //获取选择的点
