在此基础上，创建线的步骤如下：

1)创建两个点并将其转换为CATISpecObjects。

double Coords[3];

Coords[0] = 0;

Coords[1] = 0;

Coords[2] = 0;

CATIGSMPoint_var spPoint1 = spGSMFactory->CreatePoint(Coords); CATISpecObject_var spSpecPoint1 = spPoint1;                  

Coords[0] = 8;

Coords[1] = 6;

Coords[2] = 7;

CATIGSMPoint_var spPoint2 = spGSMFactory->CreatePoint(Coords);

CATISpecObject_var spSpecPoint2 = spPoint2;

2) 利用创建的点创建一条线，并将其转换为CATISpecObject

CATISpecObject_var  spSupport = NULL_var;

CATIGSMLinePtPt_var spLine1 = spGSMFactory->CreateLine(spSpecPoint1, spSpecPoint2, spSupport);

CATISpecObject_var spSpecLine1 = spLine1;

3) 更新创建的线，并将其添加到视图中。

spSpecLine1->Update();

CATIGSMProceduralView_var spCurObj = spLine1;

spCurObj->InsertInProceduralView();
