 That's it. You have basically created your cross section, disguised as a projected elevation. You now need to export it as a PDF. That's it. You have basically created your cross section, disguised as a projected elevation. You now need to export it as a PDF.
  
-Create a "​map"​ in the survey level where you imported the .th2 file, with its projection matching the scraps ("​[elevation 355]"​). Add all the scraps to it. If you are using automatic altitude colouring (rather than a [[examples#​Colour Palette Scales - Lookups|lookup]]),​ and you would like it to use the correct colours, create a new map at the top-most level with the projection set accordingly. Tell it to include the map of scraps. Then to make it [[tips:Making a subset of the cave take its altitude colours from a larger part of the cave|use the colours for the main survey]], tell it to include the **surveys** containing the data for the highest and lowest passages in the part of the cave that your regular plan survey will include (the survey where you want to render the cross section). Normally, this will be the complete data for the whole cave.+Create a "​map"​ in the survey level where you imported the .th2 file, with its projection matching the scraps ("​[elevation 355]"​).

 Create a new "​thconfig"​ file, which will project the map on the correct bearing - 355 for the demonstration. Use the "​select"​ command to select the map. Create a layout that will hide all the survey centreline, leaving only the cross section scraps. Tell it to colour by altitude. If you would like the cross sections to display at a different scale than the main survey, use the "​scale"​ option to change it. Use the various options to completely hide the legend, title, scale bar and north arrow. Create a new "​thconfig"​ file, which will project the map on the correct bearing - 355 for the demonstration.
