标题: CAA 循环中出现更新问头
  //通过拓扑获取选定边界上小的边界曲线段的个数，对每个小曲线段进行外插延伸
      int index;
for(index=1; index<=LISTCellB.Size();index++)
{
      //将每个小曲线段小曲线段特征化
      CATIGSMBoundary_var spGSMBoundary = pFact->CreateBoundary(spEdgeElem,SpecObj2,BOUNDARY_NO_PROPAG
      if (NULL_var == spGSMBoundary){cout<<"Create Boundary Failed!"<<endl;}
      CATIGSMExtrapol_var _spExtrapolSurf = pFact->CreateExtrapOl(spGSMBoundary,SpecObj2,ickStart,CATGSMTangentContinuity,CATGSMTangentBorder,FALSE,CATGSMNoPropagation);//创建外插延伸
      if(_spExtrapolSurf==NULL_var)
      {
            cout<<"创建延伸失败" <<endl;
            continue;
      }
   else
   {
            cout<<"创建延伸成功"<<endl;
         CATISpecObject_var spSpecTmp=_spExtrapolSurf;
            if (spSpecTmp==NULL_var){cout<<"获取CATISpecObject类型失败"<<endl;}
         CATISpecObject_var ispInputParent=spGsmTool;
         rcc=InsertInProceduralView(spSpecTmp,ispInputParent);//放到GSMTOOL里面
         HRESULT rc=ExtrapolUpdate(spSpecTmp);
         if (FAILED(rc))
         {
               cout<<"无法更新!!!"<<endl;
            CATISpecObject_var ispInputParent=spGsmTool;
            ispInputParent->Remove(spSpecTmp);
            spSpecTmp=NULL_var;
            continue;
         }
         else
      {
            cout<<"成功创建外插延伸,开始判断"<<endl;
         //判断方法：将外插延伸得到曲面的四个角点投影，并通过直线的夹角判断
         if (_piAngle<=0.05)
         {
               cout<<"第"<<index<<"次试拉伸的曲面片满足要求"<<endl;
               break;
         }
         else
         {
                  cout<<"该试拉伸的曲面片不满足要求,继续拉伸"<<endl;
                  CATISpecObject_var ispFather = spSpecTmp->GetFather();
                  ispFather->Remove(spSpecTmp);
                  spSpecTmp=NULL_var;
         }
   }
}
}
现在出现的问题就是将第一次外插延伸出的曲面删去以后，从第二次外插延伸开始出现更新问题，说是The Handle is NULL;
请问高手，哪边除了问题。在线等答案
