标题: 一个关于CAA中测量重心的问题，请大家帮忙看看。
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。

piInertia = NULL;

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。。。

没人知道是怎么回事么？
