There should be no problem sending a Gantt chart to a pdf file, I do it all
the time and it's incredibly simple. The ability to save to pdf is NOT an
export function, it is a print function, and the ability to do it is not
innate in any of the Office programs. You must have installed a pdf
creation application, either the full Adobe Acrobat (the full application,
not just the freeware reader) program or there are a number of
shareware/freeware pdf writers out there you can find by Googling "pdf" that
you could use as alternatives. Once installed, the pdf maker appears as a
printer in your list of installed devices. In Project then, you create the
view you want and print it to the pdf device just like you'd send it to
paper hard copy.
Creating a pdf file is not the same thing as exporting the Gantt chart to
subsequently incorporate it into a Word document or Powerpoint presentation.
To do that, set up your view so you see the information you want to move
over to the other Office application, then click the little camera button at
the right hand end of the toolbar to capture the view as a gif image file
which you can then drop as a picture into any application you wish. Be
aware that Gantt charts usually have a lot of information and skrunching it
down to fit on one page in Word or one slide in Powerpoint might make it
awfully small and hard to read.
