Hello I have been working on a largish survey project (25km surveyed in month) for the last few months. Each section of cave is split into scraps and compiled with the a file like survey The_Ashes_Seriesth import The_Ashes_Series.3d -surveys use input The_Ashes_Series.th2 map The_Ashes_SeriesMap -title "The Ashes Series" The_Ashes_SeriesScPl1 The_Ashes_SeriesScPl2 The_Ashes_SeriesScPl3 The_Ashes_SeriesScPl4 The_Ashes_SeriesScPl5 The_Ashes_SeriesScPl6 The_Ashes_SeriesScPl7 The_Ashes_SeriesScPl8 endmap join The_Ashes_SeriesScPl1 The_Ashes_SeriesScPl2 -smooth on join The_Ashes_SeriesScPl2 The_Ashes_SeriesScPl4 -smooth on join The_Ashes_SeriesScPl4 The_Ashes_SeriesScPl3 -smooth on join The_Ashes_SeriesScPl3 The_Ashes_SeriesScPl5 -smooth on join The_Ashes_SeriesScPl5 The_Ashes_SeriesScPl6 -smooth on join The_Ashes_SeriesScPl5 The_Ashes_SeriesScPl7 -smooth on #join The_Ashes_SeriesScPl7 The_Ashes_SeriesScPl8 -smooth on Endsurvey As you can see I am using survex files direct. This works fine. However when I come to compile the whole cave, rather than copying the above text into another document I have tried to include the file. However, as it is in a survey the station names get prefixed. The above also imports the 3d file, but in the overall compilation, I need to use the compiled 3d file. I end up having to comment out the survey, end survey and import lines, which becomes tedious. This will get worse when we try to put lots of caves on the same map. Am I missing something?
