CATIA二次开发入门教程---15 通过点击屏幕创建点
通过点击屏幕，自动创建点，这里直接建立了一个简单的对话框，通过pushbutton来添加一个回掉函数，函数里面去执行创建点的类。

void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
  // Add your code here
   CreatePointCmd *createPoint = new CreatePointCmd();
}

新建一个catia 的命令，名称为 CreatePointCmd ，接下来要做的就是在 action one 里面进行点的创建，代码如下：

CATBoolean CreatePointCmd::ActionOne( void *data )
{
  // TODO: Define the action associated with the transition
  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

cout<<"Point coordinates:" << point3D.GetX() << "," << point3D.GetY() << "," << point3D.GetZ()<<endl;

  //设置Container(非根节点)
  //获得Editor
  CATFrmEditor* pEditor = CATFrmEditor::GetCurrentEditor();
  //得到当前对象的文档
  CATDocument * pDocument = NULL ;
  //取得当前活动对象
  CATPathElement activePath = pEditor->GetUIActiveObject();
  //取得当前活动的product
  CATIProduct *pActiveProduct = (CATIProduct *)activePath.SearchObject(CATIProduct::ClassName());
  //当前活动对象不存在
  if (pActiveProduct == NULL)
  {
pDocument = pEditor->GetDocument();
  }
  else
  {
CATIProduct_var spRef = pActiveProduct->GetReferenceProduct();
//当前对象的引用对象是否存在
if ( NULL_var == spRef )
{
   return FALSE;
}
//当前对象的链接对象
CATILinkableObject * piLinkableObject = NULL;
HRESULT rc = spRef->QueryInterface( IID_CATILinkableObject, (void**)& piLinkableObject );
if ( FAILED(rc) )
{
   piLinkableObject->Release();
   piLinkableObject = NULL ;
   return FALSE;
}
//得到当前对象的文档
pDocument = piLinkableObject->GetDocument();
piLinkableObject->Release();
piLinkableObject = NULL ;
if ( NULL == pDocument)
{
   return FALSE;
}
  }
  //得到文档容器集
  CATIContainerOfDocument * pIContainerOfDocument = NULL;
  HRESULT rc = pDocument->QueryInterface(IID_CATIContainerOfDocument, (void**)&pIContainerOfDocument);
  if (FAILED(rc))
  {
//pIContainerOfDocument->Release();
pIContainerOfDocument = NULL ;
return FALSE;
  }

  //获得Document
  CATIContainer* _pContainer = NULL;
  //获得SpecContainer
  HRESULT hr = pIContainerOfDocument->GetSpecContainer(_pContainer);

  //GSM工厂
  CATIGSMFactory_var spGSMFactory = NULL_var;
  //设置工厂
  spGSMFactory = _pContainer;
  CATIGSMPoint_var spPoint = spGSMFactory->CreatePoint(point3D);
  CATISpecObject_var spSpecPoint= spPoint;
  CATIGSMProceduralView_var spSndPntObj = spSpecPoint;

  //*将点显示在屏幕上
  spSndPntObj->InsertInProceduralView();
  //更新点对象
  spSpecPoint->Update();

  return TRUE;
}

效果如下：

_Indication指的是什么呀
