如何得到矩形GROUP的四个端点？
我图中有个矩形的GROUP实体，如何通过程序得到这个GROUP的四个端点坐标？ 上传一个例图，望高手指教 写了一点,没时间写了,你自己再改改吧.Sub test()
Dim group(0 To 3) As AcadLine
Dim point As Variant
Dim sset As AcadSelectionSet
Dim entry As AcadEntity
Dim i As Integer
ThisDrawing.SendCommand "prompt" & "请选择"
point = ThisDrawing.Utility.GetPoint()
For i = 0 To ThisDrawing.SelectionSets.Count - 1
If ThisDrawing.SelectionSets.Item(i).Name = "ss1" Then ThisDrawing.SelectionSets.Item("ss1").Delete
Next i
Set sset = ThisDrawing.SelectionSets.Add("ss1")
sset.SelectAtPoint point
Set group(0) = sset.Item(0)
Set group(1) = sset.Item(1)
Set group(2) = sset.Item(2)
Set group(3) = sset.Item(3)
Dim pos(0 To 7) As Variant
pos(0) = group(0).StartPoint
pos(1) = group(1).StartPoint
pos(2) = group(2).StartPoint
pos(3) = group(3).StartPoint
MsgBox pos(0)(0) & " " & pos(0)(1) & " " & pos(0)(2) & vbCrLf & pos(1)(0) & " " & pos(1)(1) & " " & pos(1)(2) & vbCrLf & pos(2)(0) & " " & pos(2)(1) & " " & pos(2)(2) & vbCrLf & pos(3)(0) & " " & pos(3)(1) & " " & pos(3)(2)
ThisDrawing.SelectionSets.Item("ss1").Delete
End Sub 谢谢老大。非常感谢，我改改
