Hello,
newbie here.
I published AutoDWF.vlx to every CAD station by batch.
When AutoDWF runs, it plots using DWF6 ePlot.pc3 right?
Ok, but the DWF has the wrong pen width and the wrong paper size.
Question: how to specify the defaults to be A0 and to use the specified CTB file for the pen? It seems that even though I specify A0 in the pc3 file, every new DWG I open, it resets to A4 with thick pens.
Can you help me please?
Thanks so much!

Xanadu AutoDWF uses two different methods depending on what do you setup for publishing - either the current layout or all layouts.
 
For all layouts, it behaves the same way as the sheet set publishing function. For a single layout, it uses PLOT via the DWF6 ePlot.pc3 "plotter". So the result may depend on your page setup and PC3 settings.

Thanks Vladimir,
yes, the problem is related to what you mentioned.
I'm using the "Model" option in AutoDWF.
I don't know how to specify the default plotter settings because only some options are stored in PC3 but the others are inside the DWG.
So I get wrong paper size and pen width in DWF files...
What I'd like t have is no user intervention....
