[Therion] Cross-sections plotted independently of cave passage

[Bruce]

Up until now I've been creating cross-section scraps and inserting them
within plan or elevation scraps using a statement like;

 

point 331.25 -43.0 section -scrap BX-Ent2PLANxs-24

 

This is how I think it is usually done(?)

It works fine most of the time, but sometimes the density of passages is
such that the cross-section needs to be on the far side of the page, or
maybe you prefer to group the cross-sections together in their own little
table.  This makes including the cross-section insertion points within plan
or elevation scraps impractical I think.

Some time back there were discussions on this forum about alternative ways
of presenting cross-sections however I am not sure if they were resolved.

 

Something in the Therion Book made me think this might give interesting
results.

1.	Add one or more cross-section scraps to a map (or maps) of type
-projection none
2.	Export those maps to a map output.

So perhaps the result below is interesting, but I'm not sure how I might
develop it further into a means of presenting the cross-sections where the
sections are not plotted adjacent to the plan or elevation of the passage.

The trouble is all the cross-section maps plot on top of each other.

 

One way might be to export each cross-section one at a time then have lots
of map-image statements to add them to a final master map.  This would be a
very messy th-config file.

Or would a plan scrap with no associated survey, and lots of 'point x y
section -scrap <scrap>' work?

 

Has anyone tried to layout cross-sections independent of the passage without
resorting to post processing?

(Example below)

 

map BX-Ent2SectionsA \

            -projection none

             BX-Ent2PLANxs-24

            BX-Ent2PLANxs-94

endmap

 

  map BX-Ent2SectionsB \

            -projection none

            BX-Ent2PLANxs-36        

            BX-Ent2PLANxs-27

 endmap

.

export map -projection none \

  -layout LayoutMapThisCave             \

  -layout LayoutMapThisCaveElev       \  

  -layout-scale  1 100    \

  -layout-scale-bar 10 m \

  -output ../Outputs/CaveSections.pdf
