标题: 请教交互式工程图元的拷贝问题
想把工程图中一个SHEET的内容拷到另一个SHEET里，现通过spcurrenView=spcurrentSheet－>GetCurrentView();
然后把spcurrentView拷贝到spNewSheet.实现过程如下.

此程序可实现自己画的工程图的拷贝及图框的拷贝。但对于由CATIA的3维图直接生成的2维工程图却不能拷贝，编译可通过，但运行出错“检测到空指针”，请教各位高手，如何入手解决呢？
问题可能是处在，交互产生的工程图，和PART文档之间的连接问题。对否？

请各位指点，多谢了！：）

ListOfVarBaseUnknown newListToCopy;
ListOfVarBaseUnknown listFromCopy;

CATIView_var spView=spSheet1->GetCurrentView();
CATISpecObject_var spViewToPaste(spView);
  listFromCopy.Append(spViewToPaste);

result = piCutAndPastableOnSourceCont -> BoundaryExtract (newListToCopy,    &listFromCopy,NULL);
      if (NULL != result)
         {
                  cout<<"........."<<endl;
         }

几位高手帮我看看呀，多谢了！

没做过，具体问题不太清楚

可以给点建议，加上粘贴方式 CATFormat *pFormat 试试

呵呵，不保证

谢谢，hick!试试看！
acoka,saeba兄，帮我看看呀，指点一二！多谢！

试了一下，“由CATIA的3维图直接生成的2维工程图”也可以的。
试试下面的source吧

CATBoolean TSTSampleCmd::ActionTwo( void *data ){

  HRESULT hr = S_OK;
  CATBaseUnknown *pUnk = _Indication2->GetElementValue();
  if (!pUnk) hr = E_FAIL;

cout << "LateType: " << pUnk->GetImpl()->IsA() << endl;

CATISheet_var spSheet2(pUnk);

CATISheet_var spSheet1(_spObject1); //_spObject1is set by last selection

if (!spSheet1)
cout << "Sheet1 is NULL" << endl;
CATIView_var spSrcView = spSheet1->GetCurrentView();
CATIView_var spTarView = spSheet2->GetMainView();

if (!spSrcView)
cout << "spSrcView is NULL" << endl;

CATICutAndPastable_var spSrcCCP(CATISpecObject_var(spSheet1)->GetFeatContainer());
CATICutAndPastable_var spTarCCP(CATISpecObject_var(spSheet2)->GetFeatContainer());

CATLISTP(CATFormat) listFmt = spSrcCCP->ListPasteFormats();

int cFmt = listFmt.Size();
for (int i = 1; i <= cFmt; i++){
cout << listFmt[i]->Name() << endl;
}

IdFormat MyFmy = "CATDrwCont";

const CATFormat* pFmt = CATFormat::GetRegisteredFormat(MyFmy);

ListOfVarBaseUnknown newListToCopy;
ListOfVarBaseUnknown listFromCopy;

  listFromCopy.Append(spSrcView);

hr = spSrcCCP -> BoundaryExtract (newListToCopy,    &listFromCopy,pFmt);
if (NULL != hr)
{
cout<<"........."<<endl;
}
else
{
cout << "BoundaryExtract1 failed" << endl << flush;
return FALSE;
}

ListOfVarBaseUnknown extractedListToCopy;
CATICutAndPastable_var spSrcCCPExt = spSrcCCP -> Extract (newListToCopy, pFmt);

int r = 0;
if (!!spSrcCCPExt)
r = spSrcCCPExt->BoundaryExtract(extractedListToCopy, NULL,pFmt);

if (0 != r)
{
      cout << "BoundaryExtract from Clipboard succeeded" << endl << flush;
      cout << "Number of objects extractedListToCopy= " << extractedListToCopy.Size() << endl;
}
else
{
      cout << "BoundaryExtract2 failed" << endl << flush;
      return FALSE;
}

cout << CATIAlias_var(extractedListToCopy[1])->GetAlias() << endl;
cout << CATIAlias_var(extractedListToCopy[2])->GetAlias() << endl;

ListOfVarBaseUnknown listPastedObjects ;
ListOfVarBaseUnknown listTargetObjects ;

listTargetObjects.Append(spSheet2);

listPastedObjects= spTarCCP -> Paste (extractedListToCopy, &listTargetObjects,pFmt);

cout << listPastedObjects.Size() <<endl;

CATISpecObject_var(spSheet2)->Update();

}

在我这里是可以的。
