Chris,
Model tab can be plotted via the core console, but not sure how a script can be written to plot all layout tabs as lisp routines will not work with UI I believe. Our company policy here is one layout tab per dwg file.
Blackbox,
I am aware of autopublish, but was not convinced and perhaps a danger a WIP drawing could be issued in error by A N Other. Although perhaps something to look into. I think there are pros and cons for both. Just like the idea of using the core console for plotting.
Cheers, Robbo.
