我想通过草图中的二维约束来实现点.1和CenterPoint的相合约束。
点.1是通过直线.1的两个顶点CreatePointBetween来建立的。
CATIGSMPointBetween_var piCenterPoint = NULL_var;
piCenterPoint = _pGSMFact->CreatePointBetween(pLinePoint1,pLinePoint2,ratioParm,CATGSMSameOrientation,CopySelectLine);
if (piCenterPoint==NULL_var)
{
cout<<"创建中点失败,请检查!!!"<<endl;
return FALSE;
}
else
cout<<"创建中点成功!!!"<<endl;
CATISpecObject_var pLineCenterPoint = NULL_var;
pLineCenterPoint=piCenterPoint;//存储中点
二维约束的实现
piSketch->OpenEdition();//关键
CATI2DConstraintFactory * spConstraint= NULL;
rc = piSketch->QueryInterface(IID_CATI2DConstraintFactory,(void **)&spConstraint);
if (SUCCEEDED(rc))
{
cout<<"查询CATI2DConstraintFactory成功"<<endl;
spConstraint->CreateConstraint( spLineFeat, NULL,CopySelectLine, NULL, NULL, NULL, NULL,
Cst2DType_On, 0, 0 );
spConstraint->CreateConstraint(spPointFeat, NULL,pLineCenterPoint, NULL, NULL, NULL, NULL,
Cst2DType_On, 0, 0);
}
piSketch->CloseEdition();
其中第一个约束可以添加,第二个约束里如将pLineCenterPoint换为pLinePoint1,则可以实现约束。
为什么是pLineCenterPoint就不能实现呢? |
