As long as the stations are visible the resulting map is fine (see kolkhoehle_ok.pdf).

After that I created a scrap with the scanned map (projection plan) and scaled it using the scale bar and the scaling tool of Xtherion map editor. I marked the location of the first survey station at the cave entrance and in the layout section of my thconfig I turned on sketch export. Unfortunately it doesn't work. The generated pdf only contains the map header (with wrong length and depth statistics btw!) and a short part of the first survey shot. I expect the whole scanned background image to be visible and in scale in the pdf. Honestly said I never got the "sketches on" working with any of my old and new maps. What I am doing wrong? Any pointer to the right direction is highly appreciated. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Best regards and thanks in advance,<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Roger <o:p></o:p></p></div><p class=MsoNormal><br><br><o:p></o:p></p><pre>_______________________________________________<o:p></o:p></pre><pre>Therion mailing list<o:p></o:p></pre><pre><a href="mailto:Therion@speleo.sk">Therion@speleo.sk</a><o:p></o:p></pre><pre><a href="https://mailman.speleo.sk/listinfo/therion">https://mailman.speleo.sk/listinfo/therion</a><o:p></o:p></pre></blockquote></div></body></html>
