導(dǎo)線型尺寸標(biāo)注用來添加旁注、說明文字，創(chuàng)建導(dǎo)線型型標(biāo)注對象用AddLeader方法，語法格式如下。

RelVal=object.AddLeader(PointsArray,Annotation,Type)

下面的程序創(chuàng)建并顯示一個有箭頭的導(dǎo)線型標(biāo)注。

Private Sub Command1_Click()
    Dim leaderobj As AcadLeader
    Dim points(0 To 8) As Double
    Dim leadertype As Integer

    Dim corner(0 To 2) As Double
    Dim width As Double
    Dim text As String
    corner(0) = 0#: corner(1) = 15#: corner(2) = 0#
    width = 30
    text = "R1.5(min)"
    Set mtextobj = acadapp.ActiveDocument.ModelSpace.AddMText(corner, width, text)
    Set annotationobject = mtextobj

    points(3) = 4: points(4) = 4: points(5) = 0
