A word about margins
It's a new world of electronic drawings, but we're still dealing with those pesky things called margins.
When you make a DWF file in AutoCAD it's important that you consider what margins to specify, and here's why.
Think about your office setup. You have your computer and your printer and your trusty AutoCAD. You want to print a set of drawings. Click Plot, select your plotter/printer (probably already selected), and click "OK." Out it comes in all its glory. Chances are, you've tweaked and honed your settings over the years to get it to work perfectly...on your print device.
But now, you're being asked to produce a DWF file. OK, no problem, same process, right? Not quite. When you print to a specific print device (your office plotter), that device's driver communicates with AutoCAD and tells it what the physical maximum printable area is. AutoCAD uses that information to set up your layout or your plot. (Most physical hardware printers can't print all the way to the edge of the paper; the printhead only travels so far.)
DWF, on the other hand, is a virtual printer. It can print all the way to the edge of the (virtual) paper, with ease. So something that looks beautiful in a DWF file, centered, all the way to the edges, clean, etc., might very well get chopped when the recipient prints it to his printer (which again will have a different "printable area").
Solution? Be less greedy and more wasteful in your use of paper. That's right. Try not to build your title blocks and your layouts to go all the way to the edges that your device supports. Dial it back to a 1/4" margin on each side and you'll be pretty sure that your DWF file will print fine just about anywhere.
How do you do this? Open the Plot dialog in AutoCAD, select your DWF printer, click Properties, and then Modify Printable Area of the sheet sizes you most commonly use so that all borders are 1/4". Then modify the same for your hardware print device (they'll have to match, since you'll be printing to both pretty commonly.) Then rejigger your title block and layouts so they fit correctly on the new, wider-margin paper you've created. A few test plots (both to the plotter and to DWF) and you're ready to go.
It's a complex topic, but worth mastering. Let me know if you think I should do a YouTube video like this, on the topic of margins.
