Exporting to PDF

Hi,
This program has been a great help whilst I have been completing my Architectural A levels
I have had some issues with exporting to a PDF file format. I have some 2D objects I want to export to PDF, when i 'choose fit to page' the object appears on the page but when I stipulate the scale between moi and actual measurements nothing appears on the page.
Just wondered if you have any suggestions as to what I'm doing wrong?
Many thanks,
Jacob
