vb6编的程序如下：可是运行总是提示我Mirror有问题：无效的过程调用或参数。我希望是全自动选择后镜像，不需人干预。
'创建选择集
Dim ss As AcadSelectionSet, mode As Integer
Dim Filtertype(0 To 2) As Integer, Filterdata(0 To 1) As Variant, Point1(0 To 2) As Double, Point2(0 To 2) As Double
Set ss = AcadDoc.SelectionSets.Add("ztLine")
'对象选择
Point1(0) = -10000: Point1(1) = 10000: Point1(2) = 0
Point2(0) = 10000: Point2(1) = -10000: Point2(2) = 0
mode = 5 '0 SelectionSetWindow;1 SelectionSetCrossing; 5 SelectionSetAll;
Filtertype(0) = 8: Filterdata(0) = "主体" '8表示图层名
Filtertype(1) = 0: Filterdata(1) = "line" '0表示对象类型
ss.Select mode, Point1, Point2, Filtertype, Filterdata '选择对象经过过滤后加进新建的选择集中
'选择两个镜像线的点
Dim pnt1(0 To 2), pnt2(0 To 2) As Double
pnt1(0) = 0: pnt1(1) = R: pnt1(2) = 0
pnt2(0) = 0: pnt2(1) = -R: pnt2(2) = 0
'进行镜像
Dim ent As AcadEntity
If ss.Count > 0 Then
For Each ent In ss
ent.Mirror pnt1, pnt2 '无效的过程调用或参数。
Next
End If
请问错在哪里？谢谢了。
