Never had this problem before...
Have a dwg with two layouts sheets that print to pdf in paper space - one layout works just fine the other NOT
Both include one view port and a few small details as pdf underlays(@ 150 kb each) in the PAPER space layout
The problem sheet - ran a very slow plot preview but it did complete a full view of the layout, then when selected to do the plot it never completes the pdf.
I tried a pdf plot of the same area in MODEL space and it previews just fine and plots to a pdf just fine.
HELP
