CAD中直线、圆弧的夹点序号
可直接构造参数，然后使用moveGripPointsAt函数来移动
if(1==val)
{
AcDbIntArray indices;indices.append(0);
AcGeVector3d offset(-10,0,0);
pLine->moveGripPointsAt(indices,offset);
}
//0
if(2==val)
{
AcDbIntArray indices;indices.append(1);
AcGeVector3d offset(10,0,0);
pLine->moveGripPointsAt(indices,offset);
}
//0
if(3==val)
{
AcDbIntArray indices;indices.append(2);
AcGeVector3d offset(0,10,0);
pLine->moveGripPointsAt(indices,offset);
}
