Really? I've had no problems with it ignoring descriptions, using the incantation "*data passage station left right up down ignoreall". This is used heavily throughout the CUCC dataset and seems to work fine for me, both in Survex 1.1 and 1.0.39.
 
I notice you talk of *passage rather than *data passage. I wondered if *passage was maybe an earlier deprecated version with some features broken, but Cavern v1.0.39 claims never to have heard of it, so presumably that was a typo.
 
Multiple values for LRUDS are an issue though; I recall Duncan+Erin complaining about this too. It's not obvious how this would be handled for passage tubes in Aven, but for the tick-marks on printed surveys there's no reason why there can't be multiple ticks.

Betreff: Fw: Syntax for vertical passages (and LRUD in general)



A query from the therion list that is relevant to survex too. These
extra measurments are just a syntax for specifying cross-sectional
info on vertical passages. Does the survex *passage stuff support such
a notation (i.e. a way of specifying a vector for a measurment)?

I also noted in Austria this year that *passage does not support '~' for
'approximately', or multiple values eg. 2(8) for e.g. general passage
a canyon floor. I use these extensively in my notes and it would be
very nice if there was some way to include them in the data so the
computer could do something useful with them.

Also ignoreall or ignore or 'description' does not seem to work in
*passage either, which is tiresome. This may just be a case of not
reading the detructions properly, but in fact it seems hat *data
passage is not actually documented yet (it is in v1.0.39 isn't it?).
That I can fix.

If there is a consensus that this is useful I could have a go at
adding it - it's probably not hard.

Hello fellows,

I've faced a problem when I started to use therion for the surveys we do. The
matter is that when we survey a vertical passage (a well) we are used to take
such sets of measurements: shot from-to, length(vertical) and 3-5
combinations of azimuth and distance.
Ex. 1-2 5m. (210' - 1,2m)(0' - 4m)(75' - 3m)(160' - 0m)
210' stands for 210 degrees etc.

And I cannot  find out how using syntax of therion to note these measurements.
Or should I change the way I do notes.

Thanks for any ideas and advises.
