<p>The files of your scanned and re-scanned sketches should be stored in the same folder
as the scanned notes, i.e. (for wallet #19) you would put them in:

<h3 id="therion">Using tunnel or therion for final survey production</h3>
<p>Use aven to print out the centre lines of the passages. Now you will have to decide whether to use Tunnel or Therion. Expo has a polciy decision on this: if it is an entirely new disconnected cave, then use Therion. If it is a passage in a cave where previously we used Tunnel, then use Tunnel. See also <a href="/expofiles/tunnelwiki/wiki/pages/Other_Cave_Software.html">Comparison of Tunnel to Other Cave Software</a>.

Take the printed centre lines on paper and redraw the survey round it, working from
the original sketches as if this was to be the final published survey. You
can "invent" details like boulders in boulder-strewn passage, but otherwise,
draw only what was recorded faithfully in the cave. If this makes your
drawing look bad - record more next time! If things really are unclear,
consider taking a copy of this drawing back into the cave to clarify it.</p>
<p>Now scan your sketch, transfer the file to the <em>expo laptop</em> and open it in Tunnel (or Therion).
Using a mouse on the screen within Tunnel (or Therion), you will then trace over the image and thus create a vector drawing of the cave.
Very detailed instructions for doing this in Tunnel are in <a href="/expofiles/tunnelwiki/wiki/pages/File_Formats.html#Raw_Sketch_Data">Tunnel Wiki: Raw Sketch Data</a>
