There is one feature I have found that does not work. . One of my four maps has a section where two passages run pretty much the same way, one directly above the other. In the single-cave map I handled this by setting the upper passage off to the side. That does not come through to the group map. The two passages are drawn on top of each other.
Bill I presume you are now referring to exported map pdf outputs? I was looking for something that fitted that description in an old copy of your Big Cavern Ranch project that I got from one of your posts last year, but didn't find anything. In general, if you select and export a map that has offsets defined, they will be honoured. I you do not specifically select a map with the offsets defined, then the scraps will be plotted in their true position - no offset. I do this intentionally for overview maps of multiple caves, as offsets at small scales (1:2,000, 1:10,000) provide a misleading impression of the cave. It seems like you have done this as well, perhaps unwittingly. Your source BigCavernRanch.th contains a survey named 'all' but there is no corresponding map defined as far as I can see. Therefore despite each of those caves referenced having maps defined, they are not used - every scrap defined is used instead. So no offsets.
From the Therion Book.
'select' Description: selects objects (surveys and maps) for export. By default, all survey objects are selected. If there is no map selected, all scraps belonging to selected surveys are selected by default for map export. You can easily control what is plotted by defining a 'map all' in your BigCavernRanch.th file (or elsewhere) and then selecting it in your 'all' thconfig. Bruce
