How to save as PDF in VB.net

Hi guys,

I've been try to get the example shown here to work for me in Visual Studio.

However, it seems to have an issue finding the following data types:

                  Dim swExportPDFData As ExportPdfData

        Dim swModel As ModelDoc2

        Dim swModExt As ModelDocExtension

        Dim swDrawDoc As DrawingDoc

and on importing it can't find:

Imports SolidWorks.Interop.sldworks

Imports SolidWorks.Interop.swconst

Im currently running Solidworks 2017 SP 0

Thank you for reading, any help would be greatly appreciated!
