1. CAD like black background and write drawing.

2. Drawing from center.

3. Printing only the drawing.

4. Hit only the border.

5. With map mode MM_HIENGLISH.

6. ...etc.

Steps:

1. Initial the canvas:

void CTestCADDrawView::DoChangeModel(CFODataModel * pModel)
{
	CSize szCanvas = CSize(1000,1000);
	pModel->SetCanvasSize(szCanvas);
	pModel->SetBkColor(RGB(0,0,0));
	pModel->SetPageBkColor(RGB(0,0,0));
	pModel->SetBorderShow(FALSE);
	pModel->SetGridColor(RGB(255,255,255));
	pModel->SetGridLineType(GRID_DOT);
}

2. Initial the map mode:

void CTestCADDrawView::OnInitialUpdate()
{
	SetCurrentModel(GetDocument()->m_pDataModel);
	CFODrawView::OnInitialUpdate();
	
	ChangeMapMode(MM_HIENGLISH);
	CSize szCanvas;
	szCanvas = CSize(2000,2000);
	SetCanvasSize(szCanvas);
	GetCurrentModel()->SetPrintOrientation(DMORIENT_LANDSCAPE);
	GetCurrentModel()->UpdatePrinter();
	EnableCreate1stPointAsCenter(TRUE);
	UpdateScrollBarSize();
	SetRulerUnit(FUNIT_CM);
	SetZoomScale(100,FALSE);
}

3. Change the printing setting:

void CTestCADDrawView::DoDrawPrintObjects(CDC *pDC,const CRect &rcPrintPage)
{
	CRect rcTruePrint(rcPrintPage);
	CRect rcCurPage = rcPrintPage;

	::LPtoDP(pDC->m_hDC, (LPPOINT) ((LPRECT)rcTruePrint), 2);

	CRgn rgnRect;
	rgnRect.CreateRectRgn(	rcTruePrint.TopLeft().x,
							rcTruePrint.TopLeft().y,
							rcTruePrint.BottomRight().x,
							rcTruePrint.BottomRight().y);

	pDC->SelectClipRgn(&rgnRect);

	// Draw back shape.
//	DoDrawBackGround(pDC,rcCurPage);
	CBrush brush(RGB(255,255,255));
	pDC->FillRect(&rcCurPage,&brush);
	brush.DeleteObject();
	
	// Draw shapes of the view.
	GetCurrentModel()->OnPrintShape(pDC,rcCurPage);
	
	// Draw tab order.
	if(m_bTabOrder)
	{
		GetCurrentModel()->OnDrawTabOrder(pDC,rcCurPage);
	}
	
	// Draw select shapes.
	if(m_bShowSelectHandle)
	{
		DoDrawSelectShapes(pDC,rcCurPage);
	}

	pDC->SelectClipRgn(NULL);
}

 and

BOOL CTestCADDrawView::OnPreparePrinting(CPrintInfo* pInfo)
{
	// default preparation
	CFODrawShape *pObj = NULL;
	CFODrawShapeSet* rList = GetCurrentModel()->GetShapes();
	int xy = 0;
	for (xy = 0; xy < rList->GetCount(); xy ++ )
	{
		pObj = (CFODrawShape *)rList->GetObject(xy);
		COLORREF crLine = pObj->GetLineColor();
		if(crLine == RGB(255,255,255))
		{
			pObj->SetLineColor(RGB(0,0,0));
		}

		COLORREF crFont = pObj->GetFontColor();
		if(crFont == RGB(255,255,255))
		{
			pObj->SetFontColor(RGB(0,0,0));
		}

		COLORREF crText = pObj->GetFontColor();
		if(crText == RGB(255,255,255))
		{
			pObj->SetFontColor(RGB(0,0,0));
		}
	}

	return CFODrawView::OnPreparePrinting(pInfo);
}

void CTestCADDrawView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
	// TODO: add extra initialization before printing
	// XD++ Library Add line.
	CFODrawView::OnBeginPrinting(pDC,pInfo);
}

void CTestCADDrawView::OnEndPrinting(CDC* pDC, CPrintInfo* pInfo)
{
	// TODO: add cleanup after printing
	CFODrawShape *pObj = NULL;
	CFODrawShapeSet* rList = GetCurrentModel()->GetShapes();
	int xy = 0;
	for (xy = 0; xy < rList->GetCount(); xy ++ )
	{
		pObj = (CFODrawShape *)rList->GetObject(xy);
		COLORREF crLine = pObj->GetLineColor();
		if(crLine == RGB(0,0,0))
		{
			pObj->SetLineColor(RGB(255,255,255));
		}

		COLORREF crFont = pObj->GetFontColor();
		if(crFont == RGB(0,0,0))
		{
			pObj->SetFontColor(RGB(255,255,255));
		}

		COLORREF crText = pObj->GetFontColor();
		if(crText == RGB(0,0,0))
		{
			pObj->SetFontColor(RGB(255,255,255));
		}
	}

	CFODrawView::OnEndPrinting(pDC,pInfo);
}
