Hello everyone - Therion 5.3 (stable) running on Fedora 14 ... I am working on a cave which has a very complex maze area. Basically the maze area can be divided into either 3 or 4 layers (depending on how you draw it) which are stacked on top of each other like a cake. I want to produce a map where the lowest part of the maze displays with the rest of the main passage, and each higher layer of the maze is offset from the layer below it So far I have figured out how to get one layer to offset and have its outline (the "preview", I think) display over the main passage. Now I want to take the next layer and have its outline display over the layer below. Here is what I think should happen in the .TH file: =============== map MainCaveMap -title "Elkton Cave - Plan View" -projection plan MainPassage@ElktonCave UpperMaze@ElktonCave [200 30 ft] above UpperMaze2@ElktonCave [200 -100 ft] above endmap map MainPassage -title "Elkton Cave - Plan View" -projection plan (many scraps, names removed for clarity) endmap map UpperMaze -title "Upper maze area" -projection plan MazeA MazeB MazeA2 preview above MainPassage endmap map UpperMaze2 -title "More upper maze" -projection plan MazeC MazeD preview above UpperMaze endmap ================ When I compile the map, it draws the offset maps correctly, However, ALL of the outlines are over the MainPassage map. I don't want that ... I want an outline of UpperMaze over MainPassage, then I want an outline of UpperMaze2 over UpperMaze. I thought that is what would happen with the "preview" directive. Does anyone have suggestion? Thanks - Bill Gee
