As the title says is this possible
Running a script seems to try to start 'DWG trueview' but this then fails at the open stage.
So is there anyway to use dxf files to create a pdf?
this is not easily possible. You can find a list of format conversions, supported by the Export-Document commandlet, on this page https://www.coolorange.com/wiki/doku.php?id=powerjobs:jobprocessor:file_format_conversion
If you want to export DXF to PDF you'll probably need to use AutoCAD as Inventor requires some form of import configuration to open DXF. As a rule of thumb you can say that almost everything can be automated that can be done through the UI. Though you can use AutoCAD with the workflow described in this article ( http://support.coolorange.com/solution/articles/22000206915-how-to-use-autocad-in-powerjobs ) it is not a small task as you also have to write a plot or export function to get your PDF.
This requires quite a bit of knowledge of the AutoCAD API
Thanks for the information that is just what I need.
All the Best
