Export pdf from VB.net

  I'm trying to make an application that would take a drawing(dwg) and convert it to pdf.  Since I can do it directly in autocad 2013, i presume that there should be a function in the API, that i could use to do the same.  So far, i tried with AcadDocument.export(filename, FileExtension, AcadSelectionSet) with no luck. I cannot put PDF as a valid file extension.


Here's my code


Public sub SaveToPDF(ByVal psfilename As String)

Dim oAutocad As AutoCAD.AcadApplication = New AutoCAD.AcadApplication()

Dim oAcadDoc As AutoCAD.AcadDocument = oAutocad.Documents.Open(psfilename, True)

Dim sFolder As String = psfilename.Substring(0, psfilename.LastIndexOf("\") + 1)

Dim sFilename As String = psfilename.Substring(psfilename.LastIndexOf("\") + 1, (psfilename.Length - psfilename.LastIndexOf("\")) - (psfilename.Length - psfilename.LastIndexOf(".") + 1))

Dim oSS As AcadSelectionSet = Nothing

Try  oSS = oAutocad.ActiveDocument.SelectionSets.Add("MySet")


     oAutocad.ActiveDocument.Export(sFolder & sFilename & ".pdf", ".pdf", oSS)

     oSS.Delete() Catch ex As Exception  success = False  oSS.Delete()  

     oSS = Nothing

End Try


For Each Doc In oAutocad.Documents




oAutocad = Nothing

end sub


Does anyone have an idea?

you will have to go through the plot-functionality using the "DWG to PDF.pc3"

That makes also more sense for setting the page-size you like to have as result.

See if this helps

    Imports System.IO
    <CommandMethod("pdfing")> _
    Public Sub TestPDF()
    End Sub
    Public Sub SaveToPDF(ByVal psfilename As String)

        Dim oAutocad As AcadApplication = New AcadApplication

        oAutocad.Visible = True

        oAutocad.WindowState = AcWindowState.acMax

        Dim success As Boolean = False

        Dim oAcadDoc As AcadDocument = oAutocad.Documents.Open(psfilename, False, "")

        'Dim sFolder As String = Path.GetDirectoryName(psfilename) 'psfilename.Substring(0, psfilename.LastIndexOf("\") + 1)

        'Dim sFilename As String = Path.GetFileNameWithoutExtension(psfilename) 'psfilename.Substring(psfilename.LastIndexOf("\") + 1, (psfilename.Length - psfilename.LastIndexOf("\")) - (psfilename.Length - psfilename.LastIndexOf(".") + 1))

        Dim oSS As AcadSelectionSet = Nothing

            Dim ftype(0) As Short
            ftype(0) = 410
            Dim fdata(0) As Object
            fdata(0) = "Model"

            oSS = oAcadDoc.SelectionSets.Add("MySet")

            oSS.Select(AcSelect.acSelectionSetAll, Nothing, Nothing, ftype, fdata)

            If oAcadDoc.Saved Then
            End If
            oAcadDoc = Nothing

        Catch ex As Exception
            MsgBox(ex.Message + vbLf + ex.StackTrace)
            success = False

            MsgBox(vbLf + "Program ended up with result of: " + success.ToString)

        End Try

        BackPlot = acDoc.GetVariable("BACKGROUNDPLOT")
        acDoc.SetVariable("BACKGROUNDPLOT", 0)
        'Updates the plot
        'Now you can use the PlotTofile method
        If PtObj.PlotToFile(Replace(acDoc.FullName, "dwg", "pdf"), PlotConfig.ConfigName) Then
            acDoc.Utility.Prompt(vbLf + "PDF Was Created")
            acDoc.Utility.Prompt(vbLf + "PDF Creation Unsuccessful")
        End If
        'If you wish you can delete th plot configuration you created

        'to its original status.
        PlotConfig = Nothing
        acDoc.SetVariable("BACKGROUNDPLOT", BackPlot)

    End Sub

Thanks guys


  I've been able to convert my drawing in a pdf.  The next step is turning my application into a windows service.  i'm not able to start autocad.  I see the process comming up in task manager but the next line ain't executed.  Is there a way to open autocad in a windows service application?

Hi Hallex.


Looks great. Is there any ways to export to pdf without open the drawing (using ReadDWGfile(...
) method.
