Hi Scott H, thanks for the reply. :)
(I am using the trial version, as we are thinking of moving from ACADlt 2015 to another CAD package. Is it maybe because I am using the trial version, or am I just missing something?)
My sheets are all set to plot in monochrome.ctb, which works fine when I preview and plot individual drawing sheets to PDF, but when I try to Publish multiple sheets to PDF, they stay in colour. The 'page setup' column is empty. I can't see any setting in Publish except 'plotter named in setup', which does print it in B & W, but saves it as individual PDF sheets. :(. When I Export to PDF, it prints to B & W just fine, except there, you don't have a choice as to which sheets you want to print. (it includes the Model Space sheet)
Hope you can help.
Kind regards Ami
