我写了一个测量零件重心的批处理程序，能通过CATIPrtPart获取CATIInertia指针，却不能从CATIInertia的重心属性。

CATSession* pSession = NULL;
   HRESULT rc = : : Create_Session(sessionName,
                        pSession);
if (FAILED(rc))

   cout <<"create session erro!" <<endl <<flush;
   return;
}

//open doc
CATDocument* pDoc = NULL;
rc = CATDocumentServices : : OpenDocument(argv[1],
                              pDoc);

      return;

//Queries on the document to get the root container
   CATInit* pDocInit = NULL;
   rc = pDoc -> QueryInterface(IID_CATInit,

if (FAILED(rc))

   return;
}

CATIPrtContainer *pSpecContainer = NULL ;
   pSpecContainer = (CATIPrtContainer*)pDocInit->GetRootContainer("CATIPrtContainer");
if (FAILED(rc)||NULL==pSpecContainer)
{
   cout <<"Query CATIPartContainer erro!" <<endl <<flush;
   return;
}

pDocInit->Release();
pDocInit = NULL;

//Retrieve CATIPrtPart

CATIPrtPart_var spPart = pSpecContainer -> GetPart();
if (NULL_var == spPart)
{
   cout <<"Retrieve CATIPrtPart_var erro!" <<endl <<flush;
   return;
}
   pSpecContainer->Release();
pSpecContainer=NULL;

//Query CATIInertia
   CATIInertia* piInertia = NULL;
rc = spPart -> QueryInterface (IID_CATIInertia,
   (void**) [$piInertia)]
   if (SUCCEEDED(rc) && NULL != piInertia)
{

}
else
   return;

piInertia->Release();
piInertia = NULL;

rc = CATDocumentServices : : Remove (*pDoc);
if (FAILED(rc))

rc = : : Delete_Session("

artmeasure_Session");
if (FAILED(rc))
{

加：
CATISpaEnvironment *piSpaEnvironment = NULL;
rc = pDoc->QueryInterface(IID_CATISpaEnvironment,
                        (void**)[$piSpaEnvironment)]
piSpaEnvironment->Init();

OK了，多谢高手指点。不过又出现单位问题。。。

//Retrieve CATIInertia's feature
  double thedensity;
  double themass;
    rc = piInertia -> GetMass([$thedensity,&themass)]
  if (SUCCEEDED(rc))
  {
    cout  <<"The Density of The Part is : "<<thedensity <<endl<<flush;
    cout  <<"The Mass of the Part is : "<<themass <<endl<<flush;
  }
  else
    return;

  double theCOGposition[3];
  rc = piInertia -> GetCOGPosition(theCOGposition);
  if (SUCCEEDED(rc))
  {
    cout <<"The COGposition is :" << theCOGposition[0] <<"  "<<theCOGposition[1] <<"  " <<theCOGposition[2] <<endl <<flush;
  }
  else
    return;

double theInertia[9];
  rc = piInertia -> GetInertiaMatrix([$thedensity,theInertia)]
  if (SUCCEEDED(rc))
  {
    cout <<"The Inertia of the Product is :"  ;
    for(int inerNum = 0; inerNum < 9; inerNum++)
    {
     if(inerNum%3==0)
       cout <<endl <<flush;
     cout << theInertia[inerNum] <<"  ";
    }
  }
  else
    return;

这段红色代码造成两种不同的打印结果（如下图中的1、2），这次因该是单位原因。一开始是标准的单位，为什么添加红色代码后就单位就改变了呢。通过什么方法可以获取和控制显示结果的单位。

欢迎灌水。。。
