急！！在程序里修改参数后模型怎么更新

我用以下代码获取了一个Part document中的所有参数，并使用CATICkeParm接口中的Valuate函数改变了参数L1的值，L1为我自己创建的用户参数，初始值为60mm，修改为100Mm，使用Valuate函数后，在命令窗中显示L1的值已经变为100，但是模型中L1的值仍然是60mm。我觉得是没有更新的问题，但是怎么更新呢？哪位高手提供一点思路啊，thank a lot in advance.
整个程序为批处理程序，使用CATDocumentServices::OpenDocument函数将一个Part.CATPart文档加载到内存中的。

代码如下，其中spPart为一个Part document的Part feature，即根节点，用CATIPrtContainer接口的GetPart()函数获取的，获取过程的代码省略了。
if (NULL_var != spPart)
  {
CATIParmPublisher * pIParmPublisher = NULL;
rc = spPart->QueryInterface(IID_CATIParmPublisher,(void**)&pIParmPublisher);
if (FAILED(rc)) cout<<"Getting interface CATIParmPublisher failed"<<endl;
if (SUCCEEDED(rc)) cout<<"Getting interface CATIParmPublisher succeeded"<<endl;
CATLISTV (CATISpecObject_var) ParaList ;
pIParmPublisher->GetAllChildren("CATICkeParm",ParaList);
int Nb = ParaList.Size();
cout<<"Para number is:"<<Nb<<endl;
CATICkeParm *pICkeParm = NULL;
int i;
CATISpecObject_var UserPara1;
for(i=1;i<=Nb;i++)
{
   CATISpecObject_var specObj = ParaList ;
   rc = specObj->QueryInterface(IID_CATICkeParm,(void**) &pICkeParm);
   cout<<pICkeParm->Name()<<endl;
   CATUnicodeString ParaName("L1");
   if(pICkeParm->RelativeName()==ParaName)
   //CATISpecObject_var UserPara1;
   UserPara1=specObj;
}
CATICkeParm *pICkeParmUser = NULL;
rc = UserPara1->QueryInterface(IID_CATICkeParm,(void**) &pICkeParmUser);
cout<<"The Value of "<<pICkeParmUser->RelativeName()<<" is:"<<pICkeParmUser->Content()<<endl;
pICkeParmUser->Valuate(0.1);
cout<<"The Value of Para "<<pICkeParmUser->RelativeName()<<" after modify is:"<<pICkeParmUser->Content()<<endl;

pICkeParmUser->Release();
pICkeParmUser=NULL;
pIParmPublisher->Release();
pIParmPublisher = NULL;
  }
运行结果为：
