求助：为什么看不到创建的块？？
求助：为什么看不到创建的块？？程序如下：
Sub Example_Add()
' 创建一新块，名称为"New_Block"
Dim blockObj As AcadBlock
' 定义块
Dim insertionPnt(0 To 2) As Double
insertionPnt(0) = 0#: insertionPnt(1) = 0#: insertionPnt(2) = 0#
' 添加块到块集合中
Set blockObj = ThisDrawing.Blocks.Add(insertionPnt, "*N")
MsgBox blockObj.Name & " has been added." & vbCrLf & _
"Origin: " & blockObj.Origin(0) & ", " & blockObj.Origin(1) _
& ", " & blockObj.Origin(2), , "Add Example"
' 在块中创建圆.
Dim circleObj As AcadCircle
Dim centerPoint(0 To 2) As Double
Dim radius As Double
' 定义圆
centerPoint(0) = 0#: centerPoint(1) = 0#: centerPoint(2) = 0#
radius = 100#
' 添加圆到块中
Set circleObj = blockObj.AddCircle(centerPoint, radius)
Set blockObj = Nothing
End Sub
请指教
还没有插入呢，那是一个无名块
