【OBDCE C#】创建梁和柱

            STFLinearMemberList myMemberList = new STFLinearMemberList();
            STFLinearMember myMember;
            Bentley.Interop.MicroStationDGN.Point3d pPt=new Bentley.Interop.MicroStationDGN.Point3d();
            Bentley.Interop.MicroStationDGN.Point3d qPt = new Bentley.Interop.MicroStationDGN.Point3d();
            
            STFSectionList sectionList = new STFSectionList();
            STFSection section;
            section = sectionList.AsSTFSection;
            section.SetName("CAO5");

            pPt.X = 0;
            qPt.X = 1000;
            pPt.Y = qPt.Y= 0;
            pPt.Z = qPt.Z = 0;
            
            myMember = myMemberList.AsSTFLinearMember;
            myMember.SetPQPoints(ref pPt,ref qPt);
            myMember.SetSTFSection(section);
            myMember.SetPlacementPoint(5);
            myMember.SetCrossSectionReflection(true);
            myMember.CreateTFFormRecipeList();
            myMember.Save(false);

各位老师好，我正在摸索通过C#创建梁柱，查阅了以往的帖子写了如上代码，发现在CreateTFFormRecipeList处OBD会崩溃掉，请问应该如何修改，如有相关代码实例不胜感激，谢谢！
