CATIA二次开发入门教程---18 创建一个点
////////获得Editor、Document、Container、设置GSMFactory
CATFrmEditor* pEditor = CATFrmEditor::GetCurrentEditor();
CATDocument *pDoc = pEditor->GetDocument();
CATIContainerOfDocument_var spConODocs = pDoc;
CATIContainer* _pContainer; //Container
CATIGSMFactory_var spGSMFactory; //GSM工厂
_pContainer = NULL;
HRESULT hr = spConODocs->GetSpecContainer(_pContainer);
spGSMFactory = NULL_var;
spGSMFactory = _pContainer;
//设置点的坐标
CATMathPoint _Point;
_Point.SetCoord(10,10,10 );
/////////////////////用以上得到的Point3D画点
CATIGSMPoint_var spPoint1 = spGSMFactory->CreatePoint(_Point); //创建一个点
CATISpecObject_var spSpecPoint1;
spSpecPoint1 = spPoint1; //Casts the point as a CATISpecObject
CATIGSMProceduralView_var spSndPntObj = spSpecPoint1;
spSndPntObj->InsertInProceduralView();
spSpecPoint1->Update();
// Add your code here
在创建任何几何对象之前，必须在激活的函数命令中添加以下代码，：CATFrmEditor* pEditor = CATFrmEditor::GetCurrentEditor();if(pEditor == NULL){ printf("error getting the FRMeditor");}CATDocument *pDoc = pEditor->GetDocument();CATIContainerOfDocument_var spConODocs = pDoc;CATIContainer* pSpecContainer = NULL;HRESULT hr =spConODocs->GetSpecContainer(pSpecContainer);if(spConODocs == NULL_var){ printf("error getting thecontainer of documents");}以上代码的主要功能是获取editor, the document and the container。CATIGSMFactory_var spGSMFactory = NULL_var;CATIPrtFactory_var spPrtFactory = NULL_var;CATICkeParmFactory_var spParmFactory = 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用于创建底层的几何对象比如点、线等。PrtFactory包含创建孔特征、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建点了，步骤如下：（1）创建一个三维数组(x,y,z)定义点坐标。double Coords;Coords = 0;Coords = 0;Coords = 0;（2）创建一个CATIGSMPoint并将其转换为CATISpecObjectCATIGSMPoint_var spPoint1 = spGSMFactory->CreatePoint(Coords);//Creates a point
CATISpecObject_var spSpecPoint1 = spPoint1; //Casts thepoint as a CATISpecObject（3）为了在CATIA显示你创建的点，必须将其添加到视图中。spSpecPoint1->Update();CATIGSMProceduralView_var spPntObj = spSpecPoint1;
spPntObj->InsertInProceduralView();
