Reading all the posts about PDF issues and tinkering with the PDF settings myself, I have found a few solutions.
For pdf issues with shaded models, try changing the Shaded View Resolution to 200 dpi or less.
For some lines not showing in PDF, as stated before, change Layer setting under Content Tab to "Visible Only".
For font issues, select Stroke All Fonts option.
Only (easiest) way to make this default is to create a Mapkey. I have one to where I click on a button and it creates a PDF and saves it using the DRW name to whatever working directory was set.
**all this is accessed through: File - Save A Copy - PDF.
