Problem with .pdf vector export
 

I'm having trouble moving a document from omnigraffle to MSWORD.

I've established that the only way that seems to work to get vector graphics is to use a .pdf format.

The problem I get is that however I export it, when I import it, I find that there's a huge wasted space on the right - about 20% of the page width is wasted.

I've tried turning margins on and off and changing the size, but no joy.

Any suggestions?

I've tried fiddling a bit more.

I find that I can crop it with Preview and that gets it to fit in the window.

It's an awkward workaround though. It'd be good to know how to export it without needing this extra step.
