Yes, it should be installed automatically, was on mine. Two buttons should show up when you're in drawing mode ~ one to save a file as a PDF, another to email a PDF ~ both icons should be in the file tool bar. But you should also be able to add them to the file tool bar while in drawing mode with 'Tools>Customize Screen'. Go to the Commands tab, File should already be active. Scroll down to find Save to PDF item and select/drag to the File tool bar. Pick the directory that your config.win normally loads from and save the changes.
While you are in drawing mode, go to 'Tools>Customize Screen>Commands'. Scroll to the bottom of the list of File Commands and find the PDF icon. Select/drag it to the File Toolbar. Save the setup. (Did I say this before? Did you try it? Did it work? Yes? No? What happened? Please don't keep us in the dark!) BTW, there is no special "setup" or "installation" of this PDF functionality. In WF 3 it should just work. Haven't heard of any problems with it (maybe I should check the PTC website?)
