CATIACAA二次開發(fā)詳細教程（5）添加一個點

在創(chuàng)立任何幾何對象之前，必需在激活的函數(shù)命令中添加以下代碼，：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(\}

以上代碼的主要功能是獲取editor,thedocumentandthecontainer。CATIGSMFactory_varspGSMFactory=NULL_var;CATIPrtFactory_varspPrtFactory=NULL_var;CATICkeParmFactory_varspParmFactory=NULL_var;spGSMFactory=pSpecContainer;spPrtFactory=pSpecContainer;spParmFactory=pSpecContainer;

以上代碼設置工廠，在這基礎上你才可以造型，GSMFactory用于創(chuàng)立底層的幾何對象譬如點、線等。PrtFactory包含創(chuàng)立孔特征、拉伸特征實體等函數(shù)。ParmFactory包含設定參數(shù)的函數(shù)。

在以上的基礎上可以創(chuàng)立點了，步驟如下：（1）創(chuàng)立一個三維數(shù)組(x,y,z)定義點坐標。doubleCoords[3];Coords[0]=0;Coords[1]=0;Coords[2]=0;

（2）創(chuàng)立一個CATIGSMPoint并將其轉換為CATISpecObject

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

30

CATIACAA二次開發(fā)詳細教程

CATISpecObject_varspSpecPoint1=spPoint1;//CaststhepointasaCATISpecObject

（3）為了在CATIA顯示你創(chuàng)立的點，必需將其添加到視圖中。spSpecPoint1->Update();

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

//

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

CATIACAA二次開發(fā)詳細教程

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二次開發(fā)詳細教程（6）創(chuàng)立一條線

初始的設定請參考上一講《CATIACAA二次開發(fā)詳細教程（5）添加一個點》。在此基礎上，創(chuàng)立線的步驟如下：

1)創(chuàng)立兩個點并將其轉換為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)利用創(chuàng)立的點創(chuàng)立一條線，并將其轉換為CATISpecObjectCATISpecObject_varspSupport=NULL_var;

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

CATISpecObject_varspSpecLine1=spLine1;3)更新創(chuàng)立的線，并將其添加到視圖中。spSpecLine1->Update();

CATIGSMProceduralView_varspCurObj=spLine1;spCurObj->InsertInProceduralView();

CATIACAA二次開發(fā)詳細教程（7）創(chuàng)立草圖Sketch

有兩種方式可以創(chuàng)立草圖：1)通過參考平面創(chuàng)立

首先獲取一個CATIPrtPart變量：

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

有了CATIPrtPart變量就可以利用其方法GetReferencePlanes()，獲取參考平面

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

然后創(chuàng)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)通過原點和兩個矢量方向

該方法是通過定義一個原點和兩個方向pH、pV進行創(chuàng)立。定義原點和方向：

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

33

CATIACAA二次開發(fā)詳細教程

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();

到這里，你已經創(chuàng)立了一個Sketch，你可以在上面創(chuàng)立任意的草圖了。創(chuàng)立好記住要將其關閉：spSketch->CloseEdition();

CATIACAA二次開發(fā)詳細教程（8）草圖上創(chuàng)立幾何圖形

在上一節(jié)的基礎上，開始創(chuàng)立草圖。首先創(chuàng)立草圖工廠：CATI2DWFFactory_varsketch2DFactory(spSketch);下面創(chuàng)立點：

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);開始創(chuàng)立線：

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);將線連接起來：

CATI2DCurve_varspCurve1(spLine1);

34

CreateAssemble(joincurves,Mergedist,FALSE);

CATISpecObject_varspCurveAssy=CurveAssy;

spCurveAssy->Update();

CATIGSMProceduralView_varspCurObj=Curveassembly;

36
