OK, a few routine syntactical things to
sort out here, no bugs.
Firstly to help debug I showed the centerline
and added debug all to the layout. Then I could see what was going on.
It was apparent that with no projection
orientation the elevation scraps were screwed up (upside down). Try it
with the original file set Footleg sent, you will see. This is expected
behaviour with a scrap drawn in one orientation and then morphed to another.
Second I pulled the map object definitions
outside of the survey structure in the th file. Not sure if this was a
problem, it’s just the way I’ve found works best for me.
Third the definitions of the elevation all
need to match. Remember that if we are using integer orientations there
are 359 possible elevation types, and if anywhere it is undefined it defaults
to ‘north’. This was the main problem here.
In the attached you will see I have added;
-projection [elevation 090 deg]
To all of the elevation scraps, the
elevation map definition in the th file and the export elevation statement
in the thconfig.
Hope this helps. I guess the Therion
Book and the wiki could have a bit more on this. Drawing elevations is
one of the very basic functions after all.
Cheers

generate a projected elevation along aspecificbearing?
This is a small learning
project, so I've attached all the files apart from the bitmaps.
I think there is a bug lurking behind these problems. I am using Therion build
5.3.6 on Windows. I tried adding a projection direction of 090 to both the
scraps in my elevations th2 file, even though only one of these scraps was
included in the map in the th file at the time. This caused a long list of
errors when trying to generate the elevation pdf. So I removed the 090 from
after the word 'elevation' in the projection box for both scraps. Including the
second scrap in the map block with no projection direction declared now results
in what looks like the output for the first scrap duplicated in the elevation
pdf with both 0 and 90 projections. Hopefully you can easily reproduce these
problems with the attached files. I've left both scraps included in the map for
the elevation. But you can comment out the 2nd one and then try to set a
projection direction of 090 on both scraps in the th2 file and get the errors.
Why does changing the projection direction for the second scrap cause the pdf
generation to fail even if that scrap is not used in the pdf?

May need to include your th and th2 files to be more
specific…
Couple of likely issues.

Subject: [Therion] How to generate
a projected elevation along a specificbearing?
I've tried
searching the wiki and Therion book to find an answer to this, but it does not
seem to feature anywhere. Not even in any examples I can find. I am trying to
draw a simple cave with a 20m vertical entrance shaft, and a couple of chambers
down a slope at the bottom. I've drawn an elevation scrap for one of these
chambers and the shaft. But when I generate an elevation map using this scrap
the shaft looks fine, but the chamber wall is a mess. So I concluded it is not
projecting the elevation along the bearing I would like. The Therion book
showed me I can put a bearing on the scrap type. So I tried elevation 90. Now
my shaft is no longer appearing anywhere near vertical in the elevation PDF and
the chamber. Can anyone help me please?
Screenshot of scrap, and pdfs with default elevation map and elevation 90
settings attached.
