GGU-STRATIG: Header data coordinate system

The second coordinate system, which relates to the output sheet, applies to the header data. The coordinates are defined in [mm] independent of any scale used. The origin is always the lower left corner of the page (x/y = 0/0). The page height, any fold markers and the page margins are defined in the "Input/Page format" menu item.

Header data can be entered and edited using the Mini-CAD system. The system can be activated via the "Graphics preferences/Header toolbar" menu item. If the right margin is modified via the "Input/Overall view" menu item the x-coordinates of the existing header data are adapted automatically by the program such that they always retain the same distance to the right margin. For example, if you expand an A4 page and increase its size to A3, the header remains at the right and is therefore in the correct position when folding the printed sheet later.
