# I have exported a .dwg file into a .pdf file with the zoom to extents flag switched off, but the drawing is not shown. Why?

When the Zoom to Extents flag is equal to false, output page parameters are taken from the layout's properties and a custom application cannot change them.

Please see the Page Setup dialog from the OdaMfcApp sample application. To open the Page Setup dialog, use File -> Page Setup from the main menu.
