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[3];

Coords[0] = 0;

Coords[1] = 0;

Coords[2] = 0;

（2）创建一个CATIGSMPoint并将其转换为CATISpecObject

CATIGSMPoint_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;

* {1 R( L3 c5 ^1 u9 q* ]9 h

spPntObj->InsertInProceduralView();
