Torsten It looks like you are using these a bit different to the way I do it, so I'll ask to be sure; Are you using 'export map' or 'export atlas'? For export map the cave is positioned in the centre of the page when I do it, and the white space margin is controlled by overlap 0.5 cm (The meaning differs between map and atlas - see The Therion Book). You can modify the cave position somewhat by forcing the page to be a bit larger in one direction using map-header 110 100 nw ie, the title and legend in this example is plotted starting 110% of the original page width to the right. For export map I think the function of size x y cm page-grid on is kind of like a debug feature so you can see how the atlas page tessellation will cut up the map (I think). I do this once my cave map exceeds the size of the page I want to use, and then I switch to using atlas. If you are exporting atlas, then you can control the position of the page tessellation using a layout like... #Set co-ord system and position of map on the atlas tessellation #------------------------------------- cs EPSG:27200 #NZ Map Grid 1949 origin-label 1 A #label type #origin = co-ords of lower left corner of first atlas page origin 2502060 6023650 380 metres Or have I misunderstood?
