Both of these updates look very useful to me.

For converting Compass survey data files into metric, you can use my Cave
Converter program.
http://wscc.darkgem.com/caveconverter/
You can read Compass data into the program, and export it as Survex format.

Therion strips most of the data apart from staions and legs out of 3D files
it generates. Colour by error and by date are not possible because that
information is not in the 3D files generated from a Therion project.
Entrances are lost too. One of the reasons I plan to add Therion to Survex

Same as Bruce (but on Windows 7). Edit line context menu items work for me

I am just starting to try and draw up my first projected elevations in
Therion (only 5 years into the project!). I have found that you cannot
reproject an elevation from one bearing onto another (Therion only includes
elevation maps containing scraps of the exact same bearing as the export

Thank you Bruce and Martin for the replies and links to further reading.
These were really helpful.
Martin, I am not sure what -flip right, left in centreline is about. I
cannot find any reference to using flip in centrelines in the Therion book.
But the -flip horizontal scrap option which both of
Possibly your walls are inside out. Do the walls appear and vanish as you
rotate the model? That is a sure sign some of your scrap boundaries are not
right. Common causes are the insides of loops not flagged as outline in, or
walls which cross other walls.

An alternative to setting smaller text size codes to 0 (to hide xs labels)
is to put the labels in a different scrap to the drawing. I have done this
with some success where I wanted more detailed text in large scale maps. I
still draw it all in the editor on one th2 file, but just move the labels
Hi Bruce,
An interesting read. I think the test of any model is how well it handles
the exceptions. In the case of my own projects (where I use my recommended
structure of course) I have cases where I have to draw up a section of cave
which spans more than one trip in one drawing (typically diffic

Having finally got around to updating my install to 5.4.1 I was trying to
work out how the line colours had appeared in the official builds (I'm on
Windows). I see the ini file entries in both xtherion.ini and
xtherion.new.ini, all commented out in both files. So I am assuming the
colours are set b
I designed a UK symbol set for just this purpose. You can pull a copy from
the British Caving Association registry where I (and many other UK cavers)
publish and share our data. See the gb_layout.thc file in the Wookey

More of a problem at scrap joins where both scraps have water area fills
adjoining is that the hash lines indicating the fill type do not align. I
work around this by drawing the entire water fill area on just one of the
scraps so that it overlaps on top of the adjoining scrap (they must be in

Hi Bill,
I generally put just one .th file in my thconfig file, and that .th file
represents all the caves I want to process with that config. My master .th
file then includes the different .th files for different caves, and also
contains the equates to link them together (where they are joined by
The correct way to average bearings is to the treat them as vectors, then
average the x and y components separately before converting the resulting
vector back to a bearing. It is likely this is what the trig functions
mentioned in this thread are doing.

In my own experience, the most common blunder which the 'measure 3 times'
method with DistoX2 catches is mis-read distance. The Disto tends to be
used in the same orientation for all 3 shots, so the compass and clino tend
to be well aligned in all 3 (regardless of how well calibrated the DistoX
is,
You might also find the Cave Converter tool I wrote of some use. It doesn't
convert to Therion, but it can read Compass.dat and convert to Survex. The
survex files are not too difficult to then convert into Therion in a text
editor:
