I'm having an issue publishing from Civil 3D 2011.
Specifically, an error message is now popping up "turn off background plotting and try to plot again."
For the sake of getting my prints, I did as the error message suggested, but I still need to fix whatever is causing this. I thought this was an issue with the print driver as I recently needed to use Land Desktop 2009 (32-bit), and ended up using a driver created with Civil 3D 2011 64-bit... I first noticed this dialog in LDC, and it seems to persist in C3D.
I've since recreated the driver, and it produces a PDF just fine when plotting one-at-a-time, but I am still getting the publish error. This PC3 is a modified version of DWG to PDF (because not everyone has the same 3rd party drivers) which I've been using successfully for +/-1 year.
TIA
