It worked well to digitize contours on a topographical map - the reason why I wrote this code, but for muddy cave sketches, it was completely useless. This was the reason, why I gave it.<div><br></div><div>And I do not think that digitizing pocket-topo sketches is a good idea, when pocket topo is vector already. May be a feature, that selectively converts pocket topo sketch line to therion line would be better, but I do not think so. When tracing these sketches, I usually do really a lot of smoothing.</div>

</div>Sometimes that worked for me. Unless there is a 'trick' it seems easier to<br>
just draw manually. A nice idea though.<br>
