I think this is what you are looking for.

i already have the 3RD site

there is another one where it is shown how to prepare the Cartouche for DGW

but cannot din what the site is?

Ok o got it - it is inside the 3RD PDF file
amidst all the details but i think it begins with page 9

that;s great thanks !

Thanks

on page 10 thee is a description on how to set up the boudary for A4 paper
QUote
select and grab the top two vertices moving them 277.4mm (25.4 X 11 inches - 2 the original Plane size) in the Z axis

does it means that the page height is 277 BU so this could be put in the N Transofrm panel?
