Bill Gee said: "My solution is to choose a map rotation early and stick with it, and also to not put images on the map until almost the last step." This presupposes that the cave will never be extended again, especially in 'unexpected' directions. Let us say that North up is chosen as a map orientation. Let us then say that before the known cave has been completely mapped a large extension is discovered that trends south-west. Then another one is found elsewhere in the system that trends east. It may be that the convenient orientation of the map will change during the course of the project. To Therion users this does not matter one jot as Therion will always rotate stuff as required. And I don't know about anyone else, but especially in complex projects I have always to return to .th2 files to tweak the exact positions (and sizes, sometimes) of labels in order to ensure best fit in the final drawing. Thus I would always (if being forced not to use a PDA for some reason) survey to use pages to their maximum extent and put up with the minor inconvenience of reading sideways whilst drawing up scraps, 'cos whatever you choose, arbitrarily, you will always be wrong at some point. As an aside this is also in part why we try to generate the finished product as a pdf directly from Therion rather than importing into another drawing program as it cuts out the need to do parts of the job twice. The drawback with this is that Therion is not quite yet as flexible as I would like, notably in the management of colour and in the availability of different fonts and text characters (ampersand, copyright symbol etc). I know - or suspect - that some of these latter issues might be solvable in MetaPost, but I'm a rubbish programmer who can just about cope with php and html but no more. Graham
