I am having problems with plotting to pdf using the dwg to pdf driver. When I plot single sheets they look great. But when I send them to the architect and he combines them with his into one pdf file some of font characters will come out as squares. I have gone into the Dwg to Pdf pc3 file / custom properties and have font handling set to capture all. Believe it is on my end but Adobe was no help and am getting desperate. Any idea's?? Believe this started after loading Adobe XI. HELP!!!
