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->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);
