Mirror用法

 1  switch (quadrantType)
 2             {
 3                 case QuadrantType.one:
 4                     db.setlayerCenter();
 5                     ids.Add(db.AddToModelSpace(arc));
 6                     db.setlayerDraw();
 7                     ids.Add(db.AddToModelSpace(line1, line2, arc111, arc222));

46                     break;
47                 default:
48                     break;
49             }

mirror后删除原有 否则会出现冲突 然后将MIRROR后的实体加入DB中
