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?

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 \
