CATIACAA二次开发详细教程（5）添加一个点

在创立任何几何对象之前，必需在激活的函数命令中添加以下代码，：CATFrmEditor*pEditor=CATFrmEditor::GetCurrentEditor();if(pEditor==NULL){

printf(\}

CATDocument*pDoc=pEditor->GetDocument();CATIContainerOfDocument_varspConODocs=pDoc;CATIContainer*pSpecContainer=NULL;

HRESULThr=spConODocs->GetSpecContainer(pSpecContainer);if(spConODocs==NULL_var){

printf(\}

以上代码的主要功能是获取editor,thedocumentandthecontainer。CATIGSMFactory_varspGSMFactory=NULL_var;CATIPrtFactory_varspPrtFactory=NULL_var;CATICkeParmFactory_varspParmFactory=NULL_var;spGSMFactory=pSpecContainer;spPrtFactory=pSpecContainer;spParmFactory=pSpecContainer;

以上代码设置工厂，在这基础上你才可以造型，GSMFactory用于创立底层的几何对象譬如点、线等。PrtFactory包含创立孔特征、拉伸特征实体等函数。ParmFactory包含设定参数的函数。

在以上的基础上可以创立点了，步骤如下：（1）创立一个三维数组(x,y,z)定义点坐标。doubleCoords[3];Coords[0]=0;Coords[1]=0;Coords[2]=0;

（2）创立一个CATIGSMPoint并将其转换为CATISpecObject

CATIGSMPoint_varspPoint1=spGSMFactory->CreatePoint(Coords);//Createsapoint

CATISpecObject_varspSpecPoint1=spPoint1;//CaststhepointasaCATISpecObject

（3）为了在CATIA显示你创立的点，必需将其添加到视图中。spSpecPoint1->Update();

CATIGSMProceduralView_varspPntObj=spSpecPoint1;spPntObj->InsertInProceduralView();所有的源代码如下：//.

//

CATStatusChangeRCMyCommand::Activate(CATCommand*iFromClient,CATNotification*iEvtDat)

{

CATFrmEditor*pEditor=CATFrmEditor::GetCurrentEditor();

if(pEditor==NULL){

printf(\r\

}

CATDocument*pDoc=pEditor->GetDocument();CATIContainerOfDocument_varspConODocs=pDoc;CATIContainer*pSpecContainer=NULL;

HRESULThr=spConODocs->GetSpecContainer(pSpecContainer);

if(spConODocs==NULL_var){

printf(\ofdocuments\

}

CATIGSMFactory_varspGSMFactory=NULL_var;CATIPrtFactory_varspPrtFactory=NULL_var;CATICkeParmFactory_varspParmFactory=NULL_var;spGSMFactory=pSpecContainer;spPrtFactory=pSpecContainer;spParmFactory=pSpecContainer;

31

doubleCoords[3];Coords[0]=0;Coords[1]=0;Coords[2]=0;

CATIGSMPoint_varspPoint1=spGSMFactory->CreatePoint(Coords);//Createsapoint

CATISpecObject_varspSpecPoint1=spPoint1;//CaststhepointasaCATISpecObject

spSpecPoint1->Update();

CATIGSMProceduralView_varspPntObj=spSpecPoint1;

spPntObj->InsertInProceduralView();

return(CATStatusChangeRCCompleted);}

CATIACAA二次开发详细教程（6）创立一条线

初始的设定请参考上一讲《CATIACAA二次开发详细教程（5）添加一个点》。在此基础上，创立线的步骤如下：

1)创立两个点并将其转换为CATISpecObjects。doubleCoords[3];Coords[0]=0;Coords[1]=0;Coords[2]=0;

CATIGSMPoint_varspPoint1=spGSMFactory->CreatePoint(Coords);CATISpecObject_varspSpecPoint1=

spPoint1;

Coords[0]=8;Coords[1]=6;Coords[2]=7;

CATIGSMPoint_varspPoint2=spGSMFactory->CreatePoint(Coords);CATISpecObject_varspSpecPoint2=spPoint2;

32

2)利用创立的点创立一条线，并将其转换为CATISpecObjectCATISpecObject_varspSupport=NULL_var;

CATIGSMLinePtPt_varspLine1=spGSMFactory->CreateLine(spSpecPoint1,spSpecPoint2,spSupport);

CATISpecObject_varspSpecLine1=spLine1;3)更新创立的线，并将其添加到视图中。spSpecLine1->Update();

CATIGSMProceduralView_varspCurObj=spLine1;spCurObj->InsertInProceduralView();

CATIACAA二次开发详细教程（7）创立草图Sketch

有两种方式可以创立草图：1)通过参考平面创立

首先获取一个CATIPrtPart变量：

CATIPrtPart_varspPart(pIPrtContOnDocument->GetPart());pIPrtContOnDocument->Release();

有了CATIPrtPart变量就可以利用其方法GetReferencePlanes()，获取参考平面

CATLISTV(CATISpecObject_var)spRefPlanes=spPart->GetReferencePlanes();

然后创立XYplane(spRefPlanes[1])

CATISketchFactory_varspSketchFactory(pSpecContainer);if(NULL_var==spSketchFactory)return(CATStatusChangeRCCompleted);

CATISketch_var

spSketch(spSketchFactory->CreateSketch(spRefPlanes[1]));

if(NULL_var==spSketch)return(CATStatusChangeRCCompleted);spSketch->OpenEdition();2)通过原点和两个矢量方向

该方法是通过定义一个原点和两个方向pH、pV进行创立。定义原点和方向：

doubleorigin[3]={0.0,0.0,10.0};doublex_dir[3]={1.0,0.0,0.0};

33

CATIACAA二次开发详细教程

doubley_dir[3]={0.0,1.0,0.0};

CATISketchFactory_varspSketchFactory(pSpecContainer);if(NULL_var==spSketchFactory)return(CATStatusChangeRCCompleted);

CATISketch_var

spSketch(spSketchFactory->CreateSketch(origin,x_dir,y_dir));

if(NULL_var==spSketch)return(CATStatusChangeRCCompleted);spSketch->OpenEdition();

到这里，你已经创立了一个Sketch，你可以在上面创立任意的草图了。创立好记住要将其关闭：spSketch->CloseEdition();

CATIACAA二次开发详细教程（8）草图上创立几何图形

在上一节的基础上，开始创立草图。首先创立草图工厂：CATI2DWFFactory_varsketch2DFactory(spSketch);下面创立点：

CATI2DPoint_varspPt_bottom_left,spPt_bottom_right,spPt_top_right,spPt_top_left;

doublept_bottom_left[2]={10.,10.};doublept_bottom_right[2]={50.,10.};doublept_top_right[2]={50.,50.};doublept_top_left[2]={10.,50.};

spPt_bottom_left=sketch2DFactory->CreatePoint(pt_bottom_left);spPt_bottom_right=sketch2DFactory->CreatePoint(pt_bottom_right);spPt_top_right=sketch2DFactory->CreatePoint(pt_top_right);spPt_top_left=sketch2DFactory->CreatePoint(pt_top_left);开始创立线：

CATI2DLine_varspLine1,spLine2,spLine3,spLine4;spLine1=

sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);

spLine2=

sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);

spLine3=sketch2DFactory->CreateLine(pt_top_right,pt_top_left);spLine4=sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);将线连接起来：

CATI2DCurve_varspCurve1(spLine1);

34

CreateAssemble(joincurves,Mergedist,FALSE);

CATISpecObject_varspCurveAssy=CurveAssy;

spCurveAssy->Update();

CATIGSMProceduralView_varspCurObj=Curveassembly;

36

spCurObj->InsertInProceduralView();

CATDocument*pDoc=NULL;

rc=CATDocumentServices::New(\if(NULL!=pDoc){

coutGetDocument();if(NULL!=pDoc){

coutQueryInterface(IID_CATInit,(void**)if(FAILED(rc)){

coutGetRootContainer(idCATIContainer);

if(NULL==piRootContainer){
