I've been experimenting with using Adobe Acrobat 6 to take atlas pdf outputs from Therion and merging multiple documents as follows; 1. Use a word processor to make a nice title page with snippets of Therion output pasted into it (Title, exploration statistics, notes, legend, 3D image from loch), then creating a pdf from it. 2. Merge the title, plan & elevation pdfs, then re-order so that we have the first plan sheet on page two, and the first elevation sheet on page three, the second elevation sheet on page four, etc, then delete any surplus pages. 3. Go through all the hyperlinks, and adjust any that seem to have been messed up. (It seems to happen that a few of them get linked to the wrong page during the merge process) If this is printed double sided, we get facing plan & elevations that relate directly to each other. On screen we can view it similarly, and we can use the hyperlinks to skip directly to the adjacent sheets as if it were an unadulterated Therion output without having to scroll past the alternate views. Possibly an optimal document that works equally well on paper as it does on screen. My preliminary trials with two or three page atlas's seem to work OK. A couple of questions.. 1. Anyone else done anything like this? 2. Any suggestions for other software packages to manipulate the pdf files (so I don't have to use my employers computer or purchase my own copy of Acrobat) 3. Any thought of adding an optional bottom-margin and right-margin to Therions atlas layout options? At present they seem to always be equal (top=bottom, left=right) and this means that there is rarely a direct alignment between the adjacent plans and elevations, especially if for example portrait plans are mixed with landscape elevations - the size <width> <height> needs to be matched for the views to be perfectly synchronised, but the navigation pane coupled with 'equal' margins means the views are misaligned.+ Bruce
