CATIA开发三维转二维

sungshing

小弟想將三维零件通过代码投影到Drawing中，选择了一个面为投影面，但是转过去视图是空的，怎么回事，求助！！代码如下
//获得主视图参考面的CATMathplane
CATIMeasurablePlane *spMeasurablePlane = NULL;
HRESULT rc = listTargetFace[1]->QueryInterface(IID_CATIMeasurablePlane,  (void**)&spMeasurablePlane);
if(FAILED(rc)||spMeasurablePlane==NULL) return /*(CATNotifTransmitToFather)*/;
CATMathPlane spResultMathPlane;
spMeasurablePlane->GetPlane(spResultMathPlane);
spMeasurablePlane->Release();spMeasurablePlane=NULL;

CATIEditor *poEditor=NULL;   
CATSession *piSession=CATSession::GetPtrSession();   
CATIIniInteractiveSession *piInteractiveSession=NULL;   
HRESULT hr=piSession->QueryInterface(IID_CATIIniInteractiveSession,(void **)&piInteractiveSession);
hr=piInteractiveSession->New("Drawing", &poEditor);
CATFrmEditor* _editor2=poEditor->GetEditor();
CATDocument* pDoc =_editor2->GetDocument();
CATIDrawing *piDrawing = NULL;
CATIDftDocumentServices *piDftDocServices = NULL;
if (SUCCEEDED(pDoc->QueryInterface(IID_CATIDftDocumentServices, (void **)&piDftDocServices)))
{
  piDftDocServices->GetDrawing(IID_CATIDrawing, (void **)&piDrawing);
  piDftDocServices->Release();
}

// Gets the drawing container  
CATISpecObject_var spDrawingSpec = piDrawing;  
CATIContainer_var spDrawingCont = spDrawingSpec->GetFeatContainer();  

// The drawing factory is implemented ont the drawing container  
CATIDrwFactory_var spDrwFact = spDrawingCont;

// We do create a view with Make Up  
CATIDftViewMakeUp *piNewViewMU = NULL;  
spDrwFact->CreateViewWithMakeUp(IID_CATIDftViewMakeUp, (void **)&piNewViewMU);

// Get the view from the MakeUp  
CATIView *piNewView = NULL;  
piNewViewMU->GetView(&piNewView);
CATFrmEditor *pCurrFrmEditor = poEditor->GetEditor();
CATPathElement oUIActPathElem = pCurrFrmEditor->GetUIActiveObject();
CATBaseUnknown* pCurrElemBase = oUIActPathElem.CurrentElement();
CATILinkableObject_var spLink(pCurrElemBase);

if(NULL_var==spLink)  
{  
  cout <<"spLink is NULL!"<<endl;
}  
piNewView->SetDoc(spLink);  
// The view has to be typed: FrontView for Interactive view.   
piNewView->SetViewType(FrontView);  

   CATIGenerSpec_var spGener(piNewView);    //=piNewView-&gt;GetGenerSpec();  
   if(NULL_var!=spGener)  
   {   
    spGener->SetProjPlane(spResultMathPlane);   
   }
   else
   {
   cout <<"spGener is NULL!" <<endl;   
   }
   
   CATISheet_var spSheet=piDrawing->GetCurrentSheet();  
   CATISheet *piNewSheet = spSheet;  
   piNewSheet->AddRef();        //So Addref is needed
   
   piNewViewMU->SetPosition(100.0,50.0);  
   
   // Let's add the view to the sheet  
   piNewSheet->AddView(piNewViewMU);  
     
   
   piNewSheet->SetCurrentView(piNewView);  
   CATI2DWFFactory_var spGeomFactory(piNewView);  
   piNewView->Update(NULL_var);
   // Memory cleaning  
   piDrawing->Release();  
   piNewSheet->Release();  
   piNewViewMU->Release();  
   piNewView->Release();  
   piInteractiveSession->Save(NULL);
