Thanks, for the response. I tried setting the "embedded font" variable to all of the options, with no change. I did do a little experimenting on my floor plan with the text, and had some strange results.
I found that I could print to PDF with no problem with leaders, text, door & window text ect... but as soon as I added a dimension, I got the warning when opening the PDF, and all of my text was gone. I'm using "Arial-Western" font in my dimensions.
