Hello everyone - I seem to be missing something. I have made this work in the past, but now it seems that Therion is totally ignoring my instructions. Argh! I have a part of the cave where a stream flow under a tourist trail overlook. The original sketches were done on two different occasions, and I have drawn them as separate scraps. When I set up the map in the .th file, I created a map for "MainPassages" and another for "LowerStream". These are then collected into a single map. The LowerStream map has options "[0 0] below". However, the compiled map always shows it ABOVE. I tried adding a "break" between the two maps. I tried adding units to the [0 0], and I tried changing the offset from [0 0] to [20 20]. None of these made any visible difference in the compiled map. I tried removing the "join" that connects the lower stream to the main passage, but all that did was make for a sloppy join. The lower stream was still above the overlook area. I have other caves where I have done this, and it worked. What am I missing? Attached is the .th file I am using. Thanks! -- Bill Gee
