Tarquin, I had confused the meaning of "extended" and "elevation"
scraps. What I really want is "elevation" where there is no projection
on a specific bearing.
I completely agree with your wish about the handling of select/unselect
pairs. Maybe in version 7 ???

create the perspective really messes with the presentation. Plain
unfolded elevations are, I think, much more useful.
I was not talking about extended elevations. I was talking about
projected elevations. They are projected on a specific bearing. That is
exactly what you are asking for, I think.
I export a new .xvi on my chosen bearing:
export map -projection [elevation 256] -fmt xvi -output "somesurvey/
somesurvey elevation256.xvi"
Then I create a new .th2 for that, and draw the passage ceiling and
floor as scraps, the same way you would normally draw walls in plan
view. Make sure each scrap has "-projection [elevation 256]", and I name
my scraps accordingly. Input that in my .th:
input "somesurvey elevation256.th2"
Add a map with "-projection [elevation 256]" and add all the relevant
scraps to it.
Extended elevation ("-projection extended") normally for potholes and
some caves.
Projected elevation ("-projection [elevation 256]") for caves where you
want to maintain the horizontal relationship between passages. I use it
for metal mines with multiple levels.
My comment about joining elevations was related to treating them like
cross-sections. I suspect that scraps of "projection none" cannot be
joined.
I don't know if you can. I have never done so. Since it relies on you
positioning them at certain coordinates within other scraps of the main
projection, it probably would not be possible.
Keeping track of multiple thconfig files is a pain. As a big-picture
item - I think that should not be necessary. The fact that it IS
necessary points to some needed improvements.
I very much agree. I would dearly love for .thconfig to have something
like:
selection
select map1@mycave
...do things...
endselection
selection
select map2@mycave
...do things...
endselection
Really hate having to maintain several different .thconfig files and
link them together. But until such a thing exists, I use what I use :)
