indeed there are station points in the scraps.
therion has their coords, 
so why input the X-Y numbers by hand ?

spare thought:
btw, something similar could apply to elevation scraps
for horizontal caves.
therion could get the plane(s) of projection from the
section line ... maybe this is kind of messy: associating
a section line to a scrap to define its projection type,
the vector normal to the line in the plane of the map ...
not well defined for extended elevations, in general.

[Therion] plan cross-section

what about manual calibration of scrap using two stations and their x  
and y difference or x, y coordinates?

[Therion] plan cross-section

2010-07-19 Thread marco corvi
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
