I am trying to automate the process of PDF printing in Revit 2017 using Revit API with Idling event handler. I am opening the Revit document using OpenDocumentFile method and not using ActiveUIDocument anywhere. This process is generating InvalidOperationException. I am not sure why is it giving the exception or whether it is allowed using Revit API.
Journal Output:
' 1:< 0 <-pushSettingsIntoDriver
' C 27-Sep-2016 14:45:22.641; 1:< ExportToRequestedFormat() : Pdf Print Exception : InvalidOperationExceptionAt least one view from the view set could not be printed.

In addition to the IsPrintable field, the other thing you'll need to check for is whether the View is actually a View Template. Use IsTemplate to check that.
