I guess we all have our own ways of working, and no one works entirely in the most efficient way, so if Jim78b only uses modelspace then so be it. He is not alone in that. I'll often get drawings sent from one of the bigger manufacturers, multi-million pound business who do the same (CAD doesn't warn me that these were drawn using anything other like some drawings would, I assume they were drawn in AutoCAD).
Plotting using LISP however is a lot quicker with less user interaction (ability to make an error....) if you use paperspace. The paper size is set up, it is all zoomed to how you want, you can turn on or off layers per viewport and colour them differently if needed, even set up a sheet to be monochrome.... there are lots of benefits to going paperspace, but back to plotting, my LISPS for plotting "PLOTA3" (or whatever plot I need) and "PlotPDF" is all I need to do,, no other action. If needed I can loop through the paperspaces easily and make a PDF Plot named the same as that. I find it much easier and quicker. The other great benefit I have is that I can batch plot the drawings, very little time saving if you have to pick areas in modelspace to plot, but massively quicker doing it be paperspaces. I'll even return the manufacturers drawings with paperspace set up.
