seems that cross-section scrap must have a projection `none',
which means that therion cannot use stations to scale it "properly".
i had to draw a vertical cave, a sequence of pits, one
on top of the next. instead of drawing a plan, with plenty of
maps shifted to the side, i preferred to draw plan cross-sections
nearby the shafts as cross-sections (with a section line marking
their position on the pit).
i would also like to have one north symbol on the map,
to mark the orientation of all the plan cross-sections.
i did it fiddling with the sources, but a "more stable"
solution is appreciated.
thanks for the help,
marco
