[Therion] strange scrap plotting

Hi Will

I really like it that you have put in place a system, and documented it in
your DDC.map.th file and the other *.map.th files.  It might be the first
time I have seen a detailed description of a structured way to organize
Therion data (apologies to those who have shared their strategies with me in
the past).  The therion wiki goes part way to achieving this, but does not
yet describe a structured scalable system.  Well, I am trying to put
something together based on what I have stumbled on and cobbled together,
but it has been a few years in the making - mostly it is hidden in the
datasets I am working on - some of it has found it's way onto the wiki


So unfortunately I have not absorbed the niceties of the system your data
uses in 5 minutes, but I'll make a few hasty comments.  It seems to be a
little complicated, but that may just be because I have not yet figured out
the greater purpose. Forgive me if I am teaching you to suck eggs, but as I
haven't yet solved the problem I'll just go through and point out the
'interesting' bits in your data.

I notice you are using therion 5.3.  Although the 'stable version' it is
quite old.

Therion 5.3.6 is much better I think.  That said, the dataset will not
compile on my system.  I get an error;

D:\Program Files\Therion\therion.exe: error --
../././scraps/DDC_20101106_1.th2 [8] -- zero scale real length

That suggests to me that the scrap has not been scaled properly (or that 5.3
is indeed better).

It has three points but no walls, so is bound to cause trouble.  Adding
walls did not help however.

On looking at this scrap I notice the names are quite cumbersome;


-name a3 at 20101106.center.DDC


If indeed the .center.DDC are 'required' in the th2 file then the system may
be a little cumbersome.  Also the station names are repeated in the id box.
This is not an error, but does seem redundant.  Therion does not require it.


Some of your files do not have the first line;

encoding  utf-8

In the past if I have excluded this then my Windows operating system and
text editors tend to screw up my data files, or not work at all.  Possibly
therion throws a fit if it's missing- I forget.  Of course the confusing
thing is that Xtherion hides the encoding line, so unless you use a
different editor you might not have noticed.


I notice that although you have quite a few drawing files the dataset only
tries to invoke one of them.  I have not tried to make the others work, but
I have noticed that if I comment out references to DDC_20101106 then I can
get nice pdfs, lists and models.


So in short, with a few minutes fiddling I cannot repeat the same error you
describe, I suspect 5.3.6 is better at trapping errors and that there is a
problem with the way you are making your scraps or a problem with the way
the system you have adopted is trying to tie the components together.

Anyone else?

Subject: [Therion] strange scrap plotting




I have been drafting a map using therion but my export is generating a very
strange PDF. All my data (line plot) plots correctly in the map, but my
scraps are all tiling on a specific station. For instance, say I have
stations A1, A2, A3, and A4 labeled in a scrap. For some reason Therion is
plotting all the station & additional points (A2,A3,A4,stalagmites, etc)
exactly at the same location as A1. My scraps also contain walls but the
walls don't plot. I have a friend who is very talented with Therion and he
has looked at my project and is not sure why it is not working correctly,
thus I am not sure if this is a bug or something that I have screwed up. My
entire project is attached to this email (thconfig in /config/, A1 is in the
lower left-hand corner of map). Any thoughts you have would be greatly


best regards,
