Try today's developement snapshot (OK - if having problems with 0.4.0, just cd xtherion, make and copy only xtherion). Instead of "scale" label, there is Scale button. If you will press it, you should be able to click both scaling points very fast. S.

No idea, I need to have a look.

The problem with the whole 'move two squares and set corner co-ords' is that it is rather innacurate. ther can be quite large errors in x-sect drawins and these are amplified by this method. If that scale is then repeated for all the x-sects in a file you could easy end up with them all being 20% too big. > I need to have a look, what can I do about -scale-like option. A scale taken from the overall map (properly scaled with stations) is that it is much more likely to be correct, and a typical avergae (not a value from the ends of the bell curve, which you might get using a random x-sect to scale all the others). So this seems to me to be much better (as well as much quicker). > > The biggest problem is finding the corner-markers. > > 100% agree.

Moving the two markers to the middle would suit me best (as to draw x-sects I am always zoomed in to max 400%, so even a big arrow could take a while to find). Could you get confused as to which marker is which and thusaccidentally reverse the x-sect? If so them either make them diff shapes or colours, or put them slightly to corners. Really I don't want to move markers - I want to place them by clicking on corner points. That would be very quick and easy. So think a button for 'next two clicks place scale markers' would be best - but maybe that is not easy to code? There is a whole load of other stuff to do with grouping x-sects and auto-placing them in a box/area, and labelling section lines and corresponding sections that also needs to be addressed, but I think that is already on the to-do list. Therion ought to make sorting out sections easier but in fact it current makes it slightly harder than hand-drawing (which was already very tedious). Terikan is a good example of a cave where sections next to passages doesn't work very well - too many underlying and overlying layers. We have a general (and very difficult) problem of what to do about labels and sections in the presence of over/under lying passages. I am not yet sure what the answers are but there is definately much room for improvement.

OK, yes, that works, but it takes 40 seconds to zoom in and another 40 seconds to zoom out again (on the largish file I have open right now), so it is still slow and tedious. Also at this scale it is not possible to see the cross-section I wish to place the scale marks next to (obscrured by therion point blobs) so putting them in the right place is difficult. I can see that this would work quite well for small enough files/fast enough computers. It should go in the wiki.

Pictures are back on the right place. Sorry.

I can generate HTML version of whole wiki or any of the existing namespaces. So just let me know I will prepare a cron script for offline version generation. It could be also downloadable from web page as compressed archive. L.
