一.下载OpenCASCADE

官网下载是： http://www.opencascade.org/getocc/download/loadocc/

我的百度云已经下载好的是：

下载后运行完毕就是这样：

二.VS2017 MFC单文档配置OpenCASCADE 环境

先将每个文件夹里的bin文件夹都添加到系统的环境变量里

然后在将bin文件夹内的dll文件全部复制一份放在C:WindowsSysWOW64里（注意我这里是64位的）你们32就放32里

在VS2017中创建一个单文档MFC项目，我的命名是OCCmfc

然后在项目属性里：

 将你们自己路径下的！！包含目录，和库目录都添加上去（看图！！）

然后在连接器-》输入-》附加依赖项里添加下面这些Lib文件名：

TKBin.lib  TKBinL.lib  TKBinTObj.lib  TKBinXCAF.lib  TKBO.lib  TKBool.lib  TKBRep.lib  TKCAF.lib  TKCDF.lib  TKD3DHost.lib  TKDCAF.lib  TKDFBrowser.lib  TKDraw.lib  TKernel.lib  TKFeat.lib  TKFillet.lib  TKG2d.lib  TKG3d.lib  TKGeomAlgo.lib  TKGeomBase.lib  TKHLR.lib  TKIGES.lib  TKIVtk.lib  TKIVtkDraw.lib  TKLCAF.lib  TKMath.lib  TKMesh.lib  TKMeshVS.lib  TKOffset.lib  TKOpenGl.lib  TKPrim.lib  TKQADraw.lib  TKRWMesh.lib  TKService.lib  TKShapeView.lib  TKShHealing.lib  TKStd.lib  TKStdL.lib  TKSTEP.lib  TKSTEP209.lib  TKSTEPAttr.lib  TKSTEPBase.lib  TKSTL.lib  TKTInspector.lib  TKTInspectorAPI.lib  TKTObj.lib  TKTObjDRAW.lib  TKToolsDraw.lib  TKTopAlgo.lib  TKTopTest.lib  TKTreeModel.lib  TKV3d.lib  TKVCAF.lib  TKView.lib  TKViewerTest.lib  TKVInspector.lib  TKVRML.lib  TKXCAF.lib  TKXDEDRAW.lib  TKXDEIGES.lib  TKXDESTEP.lib  TKXMesh.lib  TKXml.lib  TKXmlL.lib  TKXmlTObj.lib  TKXmlXCAF.lib  TKXSBase.lib  TKXSDRAW.lib

然后打开项目后在stdafx.h中添加这些要用到的头文件：

#include <BRepTools.hxx>  #include <Standard_DefineHandle.hxx>  #include <DsgPrs_LengthPresentation.hxx>  #include <GCPnts_TangentialDeflection.hxx>  #include <Geom_Axis2Placement.hxx>  #include <Geom_CartesianPoint.hxx>  #include <Geom_Line.hxx>  #include <Geom_Surface.hxx>  #include <BRepAdaptor_Surface.hxx>  #include <GeomAbs_CurveType.hxx>  #include <GeomAdaptor_Curve.hxx>  #include <GeomTools_Curve2dSet.hxx>  #include <gp_Vec.hxx>  #include <Graphic3d_NameOfMaterial.hxx>  #include <MMgt_TShared.hxx>  #include <OSD_Environment.hxx>  #include <Precision.hxx>  #include <Prs3d_IsoAspect.hxx>  #include <Prs3d_LineAspect.hxx>  #include <Prs3d_Projector.hxx>  #include <Prs3d_Text.hxx>  #include <Quantity_Factor.hxx>  #include <Quantity_Length.hxx>  #include <Quantity_NameOfColor.hxx>  #include <Quantity_PhysicalQuantity.hxx>  #include <Quantity_PlaneAngle.hxx>  #include <Quantity_TypeOfColor.hxx>  #include <SelectMgr_EntityOwner.hxx>  #include <SelectMgr_SelectableObject.hxx>  #include <SelectMgr_Selection.hxx>  #include <SelectMgr_SelectionManager.hxx>  #include <SelectMgr_ListOfFilter.hxx>  #include <SelectMgr_Filter.hxx>  #include <StdSelect_EdgeFilter.hxx>  #include <StdSelect_ShapeTypeFilter.hxx>  #include <Standard_Boolean.hxx>  #include <Standard_CString.hxx>  #include <Standard_ErrorHandler.hxx>  #include <Standard_Integer.hxx>  #include <Standard_IStream.hxx>  #include <Standard_Macro.hxx>  #include <Standard_NotImplemented.hxx>  #include <Standard_OStream.hxx>  #include <Standard_Real.hxx>  #include <StdPrs_Curve.hxx>  #include <StdPrs_Point.hxx>  #include <StdPrs_PoleCurve.hxx>  #include <TCollection_AsciiString.hxx>  #include <TColgp_Array1OfPnt2d.hxx>  #include <TColgp_HArray1OfPnt2d.hxx>  #include <TCollection_AsciiString.hxx>  #include <TColStd_HSequenceOfTransient.hxx>  #include <TColStd_MapIteratorOfMapOfTransient.hxx>  #include <TColStd_MapOfTransient.hxx>  #include <TopExp_Explorer.hxx>  #include <TopoDS.hxx>  #include <TopoDS_Compound.hxx>  #include <TopoDS_Shape.hxx>  #include <TopoDS_Solid.hxx>  #include <TopoDS_Vertex.hxx>  #include <TopExp.hxx>  #include <TopTools_HSequenceOfShape.hxx>  #include <UnitsAPI.hxx>  #include <V3d_View.hxx>  #include <V3d_Viewer.hxx>  #include <WNT_Window.hxx>  #include <Prs3d_PointAspect.hxx>  #include <AIS_Point.hxx>  #include <AIS_InteractiveContext.hxx>  #include <AIS_Shape.hxx>  #include <BRep_Tool.hxx>  #include <BRepAlgoAPI_Fuse.hxx>  #include <BRepBuilderAPI_MakeEdge.hxx>  #include <BRepBuilderAPI_MakeFace.hxx>  #include <BRepBuilderAPI_MakeWire.hxx>  #include <BRepBuilderAPI_MakeVertex.hxx>  #include <BRepBuilderAPI_Transform.hxx>  #include <BRepPrimAPI_MakeCone.hxx>  #include <BRepPrimAPI_MakeRevol.hxx>  #include <BRepFilletAPI_MakeFillet.hxx>  #include <BRepBuilderAPI_Copy.hxx>  #include <BRepBuilderAPI_MakePolygon.hxx>  #include <BRepLib.hxx>  #include <BRepOffsetAPI_MakeThickSolid.hxx>  #include <BRepOffsetAPI_ThruSections.hxx>  #include <BRepPrimAPI_MakeCylinder.hxx>  #include <BRepPrimAPI_MakePrism.hxx>  #include <BRepPrimAPI_MakeTorus.hxx>  #include <BRepAlgoAPI_Section.hxx>  #include <BRepPrimAPI_MakeSphere.hxx>  #include <BRepFeat_SplitShape.hxx>  #include <TColgp_HArray1OfPnt.hxx>  #include <GeomAPI_Interpolate.hxx>  #include <GC_MakeArcOfCircle.hxx>  #include <GC_MakeSegment.hxx>  #include <GC_MakeCircle.hxx>  #include <GCE2d_MakeSegment.hxx>  #include <gp.hxx>  #include <gp_Ax1.hxx>  #include <gp_Ax2.hxx>  #include <gp_Ax2d.hxx>  #include <gp_Dir.hxx>  #include <gp_Dir2d.hxx>  #include <gp_Pnt.hxx>  #include <gp_Pnt2d.hxx>  #include <gp_Trsf.hxx>  #include <gp_Vec.hxx>  #include <Geom_CylindricalSurface.hxx>  #include <Geom_Plane.hxx>  #include <Geom_Surface.hxx>  #include <Geom_TrimmedCurve.hxx>  #include <Geom2d_Ellipse.hxx>  #include <Geom2d_TrimmedCurve.hxx>  #include <TopExp_Explorer.hxx>  #include <TopoDS.hxx>  #include <TopoDS_Edge.hxx>  #include <TopoDS_Face.hxx>  #include <TopoDS_Wire.hxx>  #include <TopoDS_Shape.hxx>  #include <TopoDS_Compound.hxx>  #include <GCPnts_AbscissaPoint.hxx>  #include <BRepAdaptor_Curve.hxx>  #include <GeomLib.hxx>  #include <GeomConvert_CompCurveToBSplineCurve.hxx>  #include <TopTools_ListOfShape.hxx>  #include <TopTools_ListIteratorOfListOfShape.hxx>  #include <TopTools_DataMapOfShapeInteger.hxx>  #include <TopTools_DataMapOfShapeReal.hxx>  #include <TopTools_IndexedDataMapOfShapeAddress.hxx>  #include <V3d_PositionalLight.hxx>  #include <V3d_DirectionalLight.hxx>  #include <V3d_AmbientLight.hxx>  #include <IGESControl_Controller.hxx>  #include <IGESControl_Writer.hxx>  #include <Interface_Static.hxx>  #include <OpenGl_GraphicDriver.hxx>  #include <Graphic3d_GraphicDriver.hxx>  

然后在OCCmfc.h文件的类里添加：

Handle(Graphic3d_GraphicDriver) m_GraphicDriver;  Handle(Graphic3d_GraphicDriver) GetGraphicDriver() { return m_GraphicDriver; }

在OCCmfc.cpp的构造函数里加上：

try {          Handle(Aspect_DisplayConnection) aDisplayConnection;          m_GraphicDriver = new OpenGl_GraphicDriver(aDisplayConnection);      }      catch (Standard_Failure) {          AfxMessageBox(L"(Error Ocured in Initializing the Opencascade graphic variable.)");      }

注意！！！如果new字符报错，那么是因为opencascade对new进行了重载，我们将每个new报错文件顶部的：

#ifdef _DEBUG  #define new DEBUG_NEW  #endif

这几行代码注释就行了

接着在OCCmfcDoc.h文件类里添加：

Handle(AIS_InteractiveContext) myAISContext;  Handle(V3d_Viewer) myViewer;  Handle(V3d_Viewer) GetViewer(void) {return myViewer;}

接着去实现文档OCCmfcDoc.cpp中类的构造函数中添加：

Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((CmOCCTApp*)AfxGetApp())->GetGraphicDriver();        myViewer = new V3d_Viewer(theGraphicDriver);      myViewer->SetDefaultLights();      myViewer->SetLightOn();        myAISContext = new AIS_InteractiveContext(myViewer);        myAISContext->SetDisplayMode(AIS_Shaded,true);      myAISContext->SetAutomaticHilight(Standard_False);

然后去去OCCmfcView.h定义类里添加：

Handle(V3d_View) myView;  

和添加要重写的这个函数：

virtual void OnInitialUpdate();  

然后去OCCmfcView.cpp文件里添加下面这个实现函数（随便添加在哪里）：

void COCCmfcView::OnInitialUpdate()    {        CView::OnInitialUpdate();            myView = GetDocument()->GetViewer()->CreateView();      myView->SetShadingModel(V3d_GOURAUD);      Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((COCCmfcApp*)AfxGetApp())->GetGraphicDriver();      Aspect_Handle aWindowHandle = (Aspect_Handle)GetSafeHwnd();      Handle(WNT_Window) aWntWindow = new WNT_Window(GetSafeHwnd());      myView->SetWindow(aWntWindow);      if (!aWntWindow->IsMapped()) {          aWntWindow->Map();      }      Standard_Integer w = 100;      Standard_Integer h = 100;      aWntWindow->Size(w, h);      ::PostMessage(GetSafeHwnd(), WM_SIZE, SIZE_RESTORED, w + h * 65536);      myView->FitAll();        myView->ZBufferTriedronSetup(Quantity_NOC_RED, Quantity_NOC_GREEN, Quantity_NOC_BLUE1, 0.8, 0.05, 12);      myView->TriedronDisplay(Aspect_TOTP_LEFT_LOWER, Quantity_NOC_WHITE, 0.2, V3d_ZBUFFER);  }

然后在这个文件中的OnDraw()函数中添加：

myView->MustBeResized();  myView->Update();  

编译运行：

三.绘制图形

在OCCmfcDoc.h中添加

 void DrawSphere(double Radius);

在OCCmfcDoc.cpp中添加函数（随便放哪）：

void COCCmfcDoc::DrawSphere(double Radius)  {      BRepPrimAPI_MakeSphere mkSphere(Radius);      TopoDS_Shape Sphere = mkSphere.Shape();      Handle(AIS_Shape) myAISSphere = new AIS_Shape(Sphere);      myAISContext->Display(myAISSphere, Standard_False);      CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;      CMDIChildWnd *pChild = (CMDIChildWnd *)pFrame->GetActiveFrame();      COCCmfcView *pView = (COCCmfcView *)pChild->GetActiveView();      pView->FitAll();  }

然后在OCCmfcView.h中添加：

void FitAll() { if (!myView.IsNull()) myView->FitAll();  myView->ZFitAll(); };

最后在OCCmfcView.cpp文件里的OnDraw()函数里添加：

pDoc->DrawSphere(6);

然后运行如下所示 画了一个图形出来：
