I am not sure I am following so bare with me.  Almost 90% of my drawings can be batch plotted as the layout is already predifend. So in any of the drawings, when opened, you can export to PDF and it works, without doing anything.

If I understatnd you, you are saying that everytime your command begins, it has to get the window coordinates again, then it may not be worth continuing.

Currnently I do everything in Windows, however I like the smoothness of how MAC version runs (clean, nice pan etc etc) and would like to start using this.  RIght now I have about 3k in drawings that co-workers do not need to interact with, just open, PDF it and send with quotes etc.  So the idea was to remove them from having to use a DWG Viewer and the plot process.  I have all the drawings created to PDF, so from this point fwd, everytime I save it prints it PDF so the PDF's they see are updated without me having to remember to PDF it.

So If my second paragraph is true, then there is probably no need to move forward as I could just keep using WIN version and the save command you did for me there.

I have attached a DWG that contains the LAYOUT that I have in probably 75% of all the drawings.  In case you would need to understand.
