This is a small learning project, so I've attached all the files apart from the bitmaps.<br><br>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?<br>

<li class="MsoNormal" style="color: navy;"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Firstly
check that the direction of the projection is the direction in which you
are looking. Ie on the elevation the direction will then be
‘into the page’. If you don’t specify a direction
then Therion assumes it is north. I would guess you have some
scraps/maps with differing projection directions, and so naturally they
are different projections. If you have for example 3 different projection
directions, then therion will make three elevations (if you ask to export
them). Look in the log file or Xtherion compiler map structure pane
for clues.</span></font></li>
<li class="MsoNormal" style="color: navy;"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Make
sure every scrap and map you want to include in this elevation has the
same projection. Many versions ago I found that Therion assumes 0 is
not the same as 000 and 20 is not the same as 020. So I always use 3
digit integers these days.</span></font></li>
<li class="MsoNormal" style="color: navy;"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Differing
coordinate systems. If you for example use a different thconfig for
the main map production and test plots of parts of the cave you might be
using different coordinate systems or declinations each time. This
will really screw up the elevations where passage is almost in the same
direction as the projection, because Therion will morph as much as
required. In this situation it often turns into a real mess.</span></font></li>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">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?<br>

settings attached.<br>
