坐標型尺寸標注用來標注零部件上某點相對于原點的垂直距離，創(chuàng)建坐標型尺寸標注對象用AddDimOrdinate方法，語法格式如下。

RetVal=object.AddDimOrdinate(DefinitionPoint,LeaderEndPoint,UseXAxis)

下面的代碼創(chuàng)建一個坐標型尺寸標注。

Private Sub Command1_Click()
    Dim dimobj As AcadDimOrdinate
    Dim definingpoint(0 To 2) As Double
    Dim leaderendpoint(0 To 2) As Double
    Dim usexaxis As Boolean
    definingpoint(0) = 12#: definingpoint(1) = 8#: definingpoint(2) = 0#
    leaderendpoint(0) = 20#: leaderendpoint(1) = 13#: leaderendpoint(2) = 0#
    usexaxis = False
    Set dimobj = acadapp.ActiveDocument.ModelSpace.AddDimOrdinate(definingpoint, leaderendpoint, usexaxis)
    ZoomExtents
End Sub
