Hi, newbie Therion user excited by the prospect of electronic maps.
My first steps have been successful, but I've got stuck. I'm using Windows
XP and Xtherion 0.5.1
I can produce centreline plots of single or multiple surveys from multiple
*.th and thconfig files in multiple directories to *.pdf, *.xvi and *.lox
files. That much I seem to understand.
I can scan *.jpg images of my surveys and trace them to produce *.th2 files
that look fine both in the map editor and the text editor. I think I
understand how this works, it seems easy enough.
When I place the following in my surveyN.th file,
input RBMtestplan.th2
map m_plan_ent -title "Map plan entrance"
scrap1
endmap
and the following in thconfig.
source surveyN.th
select m_plan_ent at n
. I get one of two results; a) a line plot that ignores the scrap and
produces only a centreline as if the scrap did not exist, or b) an error;
Mostly I get the error; viz
"D:\Program Files\Therion\therion.exe: error -- RBMtestplan.th2 [7] --
invalid length reading -- -scale"
(Sometimes the error is -- invalid length reading -- -projection)
And the offending line is;
scrap scrap1 -projection plan -scale [-128 -1296 880 128 0.0 0.0 25.60 0.0
meters]
This "seems" to follow the required syntax, and is generated automatically
by the map editor.
The samples I downloaded work fine, and I can not see my trial differs
materially.
Both results are unsatisfactory. I would like a drawing of the cave.
I suspect I may not be scaling the sketched survey stations to the
centreline survey stations correctly(?)
Any suggestions what I am doing wrong?
Any suggestions how I can go about debugging the problem?
Thanks
Bruce Mutton
