请教：VBA代码获取图框对角点，打印时发生了偏移？
我用代码获取图框的对角点，还画了一条直线看看对不对，直线位置是对的。但是以这两个对角点来确定打印范围并打印的时候，发现实际的打印范围偏移了，如下图：但是在有的文件里打印却是正常的！
请教各位老师：这是什么原因导致的？代码如下：
Option Explicit
Sub 点选获取打印图框() '通过鼠标选择图框，获取图框的对角点存于数组中，然后批量打印。
Dim EntObj As AcadEntity, PickPot As Variant
Dim MinPt As Variant, MaxPt As Variant
Dim arr(), m%, Temp$, NameStr$
NameStr = InputBox("请输入要打印的图框名称，多个名称请用逗号“，”隔开。", "友情提醒:", "横向图框，纵向图框，砖型图，砖型图框")
Do
X:
On Error Resume Next '鼠标单击空白处，下面选择实体的语句会出错中断。
Set EntObj = Nothing '清除EntObj前一次的值
Temp = "" '清除Temp前一次的值
With ThisDrawing
.Utility.GetEntity EntObj, PickPot, "请选择图框:"
Temp = EntObj.ObjectName
If Len(Temp) = 0 Then
If MsgBox("您未选择任何实体对象，是否退出选择？", vbYesNo + vbInformation, "友情提醒:") = vbYes Then
Err.Clear '清除错误
Exit Do
Else
GoTo X
End If
ElseIf Temp"AcDbBlockReference" Then
MsgBox "您选择的实体对象不是块参照对象，请选择图框块参照对象。" _
& vbCrLf & "若要退出选择，请单击空白处。"
GoTo X
Else
If InStr(NameStr, EntObj.EffectiveName) > 0 Then
m = m + 1
ReDim Preserve arr(1 To 2, 1 To m)
EntObj.GetBoundingBox MinPt, MaxPt
arr(1, m) = MinPt
arr(2, m) = MaxPt
End If
End If
End With
Loop
批量打印 (arr)
End Sub
