Creating pdf files in Acad 2009...Missing information

When making pdf files from Acad 2009 we get random sheets that are missing lines, text...etc. We can go back and make a new pdf and the information is there, totaly random. All layers are on and not on defpoints, etc. Any help would be greatly appreciated.

I experience this as well from time to time and have yet to find an awnser, I get it occasionally when printing hard copies as well.

I don't get it with hard copies just pdf files. The randomness is what is killing me.

I suspect a driver issue but have no proof ....

did you wait until converting done? Because when you are converting sometimes if converting not done it will cause missing of some lines...

I have AutoCAD LT 2009 and have those same issues. I downloaded AutoDesk TrueView and use that to plot to pdf instead of AutoCAD. Issues gone.

I will have to try the TrueView, thanks

Driver issue even though hard copies never have the problem? Could be, I think it is in the creation of the pdf which leads me to suspect the Acrobat Professional program may be the problem.
