When I create a NEVRON Diagram Document I configure PageSettings (size, margins, orientation) as in this example :
  NDrawingDocument1.Settings.PageSettings.PaperKind = Printing.PaperKind.A3
  NDrawingDocument1.Settings.PageSettings.Landscape = True
  NDrawingDocument1.Settings.PageSettings.MarginsLeft = 100
  NDrawingDocument1.Settings.PageSettings.MarginsRight = 100

In fact print preview window shows this values.
But when I click PDF EXPORT button the export preview shows different values (for example A4 instead of A3)
It's possible to configure, at runtime, the PDF EXPORT preview settings?
