Jean-FlorentBriefly, Therion works best when you give it small independent
chunks of data (xvi, one days survey, small scraps, one days th2). These should
never be amalgamated with the next days survey, but are instead connected up
using surveys made of sub-surveys and maps made of sub-maps.Each xvi and the
should only be created once and never amended with the next days survey. Else
the effects you describe come into play. Putting everything in one big file is
probably the worst possible approach. Good approaches are described in a number
of places on the wiki. I just don't have good access at the moment to provide
specific links. BruceSent from my Galaxy

<[email protected]> Subject: [Therion] Good practices for xvi files? Hi all,I
have some problems with xvi files so I wonder if I do things the right way.Like
many of you I guess, I use to draw incrementally. That is, I have a therion
project that compiles to a map of a cave we are currently exploring and when we
discover new stuff, we survey it and I add it to the map with the following
steps:1. Add the new data in a new th file to the project folder.2. Compile to
update the xvi file.3. Open the drawing with xtherion and draw the part of the
cave corresponding to the new data.4. Compile to get a pdf.(in particular in
this example there is a unique xvi file and a unique th2 file for the whole
cave)The problem is in step 3 when I open the drawing with xtherion. Sometimes
the updated xvi is shifted compared to the existing drawing, possibly because
it does not have the same dimensions as previously. This is annoying but can be
fixed by manually positioning it. However if I close a loop then the xvi
centerline is distorted (to distribute along the loop the unavoidable error) so
in xtherion the previously draw map does not correspond at all to that
centerline.Problems:- I have to position the xvi manually (this cannot be
avoided I suppose)- Only the new parts of the cave can be drawn on the xvi,
because the old ones do not correspond anymore. In particular I cannot easily
rework previously drawn parts of the cave.I tried to think of different
solutions:a) Generate a different xvi file for each time I add data, so that I
can always open in xtherion an xvi file that matches the part of the drawing I
am interested in.b) Accept that the xvi file will only match the latest part of
the drawing and each time I add data, fix it position with respect to the
station where the new data starts.c) Use a version control software like git,
so that I can easily find in the history a version of the xvi file matching the
part of the drawing I want to work on. (I would like to avoid this option
because when teaching therion to beginners there is already a lot to tell and I
do not want to add git on top of that.)What about you, how do you deal with
that?Best,Jean-Florent._______________________________________________Therion
