You can use adobe Acrobat to convert the file for you.
You will need to create a PLT file and then this would convert that file into a PDF file.
Imports ACRODISTXLib Public Class Class1 Function PrintPDF(ByVal pltName As String, ByVal PDFName As String) As Boolean Dim rtnValue As Boolean Dim myPDF As PdfDistiller = Nothing If myPDF Is Nothing Then myPDF = New PdfDistiller End If Try rtnValue = myPDF.FileToPDF(pltName, PDFName, "") Catch ex As Exception rtnValue = False MsgBox("Error Creating PDF File:" & PDFName & vbCr) End Try End Function End Class
DWF/PDF Batch Publish for AutoCAD
This plugin can be used with AutoCAD to simplify the process of publishing sets of drawings to DWF and/or PDF. It runs as a command within AutoCAD - as opposed to a separate executable - and uses a separate executable to monitor AutoCAD's health and restart it, as needed. The status of the batch publishing operation is stored to disk, allowing it to pick up from where it left off and also for any failed documents to be retried without starting from scratch. A setting is available to only publish drawings that have been modified since they were last published, making it easier to publish sets of documents on a regular basis.
