Task exporting flat pattern to DXF

Hello,

i created a task to directly export the flat pattern to DXF but code not work

Can anybody tell me what's wrong?

Option Explicit

Sub main()

    Dim swApp                   As SldWorks.SldWorks
    Dim swModel                 As SldWorks.ModelDoc2
    Dim vConfNameArr            As Variant
    Dim sConfigName             As String
    Dim nStart                  As Single
    Dim i                       As Long
    Dim bShowConfig             As Boolean
    Dim bRebuild                As Boolean
    Dim bRet                    As Boolean
    Dim CurFeature              As SldWorks.Feature

    Set swApp = CreateObject("SldWorks.Application")
    Set swModel = swApp.ActiveDoc

' Is document active?

If swModel Is Nothing Then

    swApp.SendMsgToUser2 "A sheet metal part must be open.", swMbWarning, swMbOk

    Exit Sub

End If

' Is it a part document?

Dim modelType As Long

modelType = swModel.GetType

If modelType <> SwConst.swDocPART Then

    swApp.SendMsgToUser2 "A sheet metal part must be open.", swMbWarning, swMbOk

    Exit Sub

End If

        vConfNameArr = swModel.GetConfigurationNames

    For i = 0 To UBound(vConfNameArr)

        sConfigName = vConfNameArr(i)
   
    If Right(sConfigName, 15) = "SM-FLAT-PATTERN" Then
   Else
bShowConfig = swModel.ShowConfiguration2(sConfigName)

bRebuild = swModel.ForceRebuild3(False)

Dim FilePath As String
Dim PathSize As Long
Dim PathNoExtension As String
Dim NewFilePath As String

FilePath = swModel.GetPathName
PathSize = Strings.Len(FilePath)
PathNoExtension = Strings.Left(FilePath, PathSize - 6)

NewFilePath = PathNoExtension + sConfigName & ".DXF"

'Export Flat Pattern
bRet = swModel.ExportFlatPatternView(NewFilePath, 1)
End If
Next i
End
End Sub
