求助啊??难了我好几天的问题了

Public Sub mi(ss As AcadSelectionSet, x1, y1, x2, y2) ''''''''''''''选择集镜像
Dim p1(2) As Double, p2(2) As Double
p1(0) = x1: p1(1) = y1: p1(2) = 0

Dim ent As AcadEntity
If ss.Count > 0 Then
For Each ent In ss
ent.Mirror p1, p2
Next
End If

End Sub Private Sub drawline(x1 As Double, y1 As Double, x2 As Double, y2 As Double, lay As String) '用指定层画直线

End Sub sub mir()'''''''对选择的线条进行镜象操作

End Sub 就是搞不懂为什么通过选择定义的点"po(2)为坐标数组" 的直线进行镜象操作没有反映啊????????????????????????????????????????????????????????? 敬请各位高手指正!!!!谢谢!!!!

雪山飞狐_lzh

通过选择定义的点"po(2)为坐标数组" 的直线是调用drawline子程生成的么？


如果是的，把drawline改写为函数，返回值就是你要的

hekaiyu

对的drawline已经是函数了。只是我没有没有写出来而已。我今天终于解决了问 体：是因为我少了一个sset.updat的原因！！！谢谢上面那为版主了！

谢谢提供思路学习了
