如何提取line的两个端点坐标。
    图形中已有若干条line直线，现在要提取line的两个端点坐标。怎样实现？

不是太难，而是太容易，总感觉到提问者是不是没有表达完整自己的问题。希望楼主能从以下代码中得到帮助，若还有其它困难，请说清楚。因为都VBA基本操作，所以没加注释。
Sub GetPointFromLine()
Dim Pt1 As Variant
Dim Pt2 As Variant
Dim Str As String
Dim Sel As AcadSelectionSet
On Error Resume Next
Set Sel = ThisDrawing.SelectionSets.Add("ssel")
If Err Then
  Err.Clear
  ThisDrawing.SelectionSets("ssel").Delete
  Set Sel = ThisDrawing.SelectionSets.Add("ssel")
End If
On Error GoTo 0
Sel.SelectOnScreen
Dim obj As AcadObject
For Each obj In Sel
  If obj.ObjectName = "AcDbLine" Then
    Pt1 = obj.StartPoint
    Pt2 = obj.EndPoint
    Str = "起点：(" & Pt1(0) & "," & Pt1(1) & "," & Pt1(2) & ")" & Chr(13)
    Str = Str & "终点：(" & Pt2(0) & "," & Pt2(1) & "," & Pt2(2) & ")"
    MsgBox Str
  End If
Next
Sel.Delete
End Sub

draw
