[求助]VBA这样的选择集怎样写

直线的起点坐标为10，25，终点的坐标为100，129，图层名为LINE1，画图之前现要判断这条线是否存在，如果存在且图层相同，则不画这条线，如果不存在或存在但图层不是LINE1就画这条线，在直线的两端分别插入两个名称为2的块，图层名为BLOCK1,再在直线两端分别插入两个单行文字“起点”“终点”，画图之前现要判断他们是否存在，块和文字同样要做与直线相同的判断。有那位大哥知道改怎么写吗？

过滤器：pnt1,pnt2先赋值
0,"line",
10,pnt1,
10,pnt2,
8,"line1"

我这样写怎么不行，而且直线都画不出来，问题出在哪里？
Sub lline()
Dim linex As AcadLine
Dim pnt1(2) As Double, pnt2(2) As Double
pnt1(0) = 10:pnt1(1) = 25:pnt1(2) = 0
pnt2(0) = 100: pnt2(1) = 129: pnt2(2) = 0
Dim sset As AcadSelectionSet
Set sset = ThisDrawing.SelectionSets.Add("temline")
Dim FilterType As Variant, FilterData As Variant
Dim gpCode(3) As Integer, dataValue(3) As Variant
gpCode(0) = 0
dataValue(0) = "LINE"
gpCode(1) = 8
dataValue(1) = "LINE1"
gpCode(2) = 10
dataValue(2) = pnt1
gpCode(3) = 10
dataValue(3) = pnt2
FilterType = gpCode
FilterData = dataValue
sset.Select acSelectionSetAll, FlterType, FilterData
If sset.Count = 0 Then
      Set linex = ThisDrawing.ModelSpace.AddLine(pt1, pt2)
    Else
      MsgBox "该线段已存在"
    End If
End Sub

搞错：），终点DXF码是11
Sub test()
On Error Resume Next
    Dim sset As AcadSelectionSet
    ThisDrawing.SelectionSets("temline").Delete
    Set sset = ThisDrawing.SelectionSets.Add("temline")
   
    Dim pnt1(2) As Double, pnt2(2) As Double
    pnt1(0) = 10:pnt1(1) = 25:pnt1(2) = 0
    pnt2(0) = 100: pnt2(1) = 129: pnt2(2) = 0
   
    Dim ft(3) As Integer, fd(3) As Variant
    ft(0) = 0: fd(0) = "LINE"
    ft(1) = 8: fd(1) = "LINE1"
    ft(2) = 10: fd(2) = pnt1
    ft(3) = 11: fd(3) = pnt2
   
    sset.Select acSelectionSetAll, , , ft, fd
   
    Dim linex As AcadLine
    If sset.Count = 0 Then
      Set linex = ThisDrawing.ModelSpace.AddLine(pnt1, pnt2)
      linex.Layer = "LINE1"
    Else
      MsgBox "该线段已存在"
    End If
End Sub
