I'm assuming you're referring to the OLE is not printing right.
Are you printing through AutoCAD's PDF writer or a 3rd party app?
I prefer PDFCreator myself (on 64bit) or CutePDF, PDF995 worked very well in XP, but I haven't used it recently.
I am using Acrobat x's PDF printer, and i also tried using Autocad's dwgtopdf printer, same result. i tried the export to pdf but that doesn't work at all, i just get a plot.log file.
I linked my excel file to my autocad drawing but when I try to print it only prints the data in the first row and the gridlines but none of the rest of the data. It even shows up this way in the preview. What setting do I have screwed up to cause this to happen? I'm using autocad 2008 btw.
