以上语句不知为何不能设置居中,加入居中语句后文字会跑到老远的地方,这是为什么?请指教red[/COLOR]

当中这样修改:
'''标注文字
Set NoObj = ThisDrawing.ModelSpace.AddText("JS121", pickedp1, Height)
'''以下这句总不对
NoObj.Alignment = acAlignmentCenter
NoObj.TextAlignmentPoint = pickedp1


'''文字
Set ElevObj = ThisDrawing.ModelSpace.AddText("2.12", pickedp2, Height)
ElevObj.Alignment = acAlignmentCenter
ElevObj.TextAlignmentPoint = pickedp2

ljpnb ，谢谢。我调试出来了。你是宁波的吧？我也是。
