[Therion] Build a map with all centerline and partial walls

[Bill Gee]

Thank you all for your suggestions and hints.  I have figured out how to 
make this work - Mostly!

Take a look at this map:

https://campercaver.net/MiscFiles/CaveSpringCave-All.pdf

This is very close to what I want.  The only problem is more of an 
annoyance.  It appears that adding the centerline as a survey makes 
Therion process the LRUDs to come up with a pseudo-wall.  I would like 
that to go away.  I tried adding "hide-symbol line wall" to the layout, 
but that made all of the walls go away.

In the thconfig file I changed the "source" line to the new .th file, 
added a symbol-hide line for cross-sections and changed the name of the 
output file on the export line.  I also changed the "select" line to 
reference MainPlan-All.

Here is how I set up the .th file:

========================
map MainPlan-All
   MainPlan
   MainCenterLine
endmap

# Create the main map to include all submaps
map MainPlan -title "CaveSpringCave (SHN-017) - Plan View" -projection plan

# X and Y upper level
X-Survey at CaveSpringCave
Y-Survey at CaveSpringCave

# Main passages
MainPassages at CaveSpringCave

# Lower stream passage
A-Entrance at CaveSpringCave
A-Survey at CaveSpringCave

# T-Survey - Small side passage off upper trunk
T-Survey at CaveSpringCave
endmap

survey MainCenterLine
   centreline

   # Define the units that will be used.
   units compass degrees
   units clino degrees
   units length feet
   units depth feet
   units tape feet
   units altitude feet
   units dimensions feet

# A separate file contains all of the survey data.  Use multiple files 
as needed
   input CaveSpringCave-Surveydata.txt

   endcentreline
endsurvey

survey CaveSpringCave -title "Cave Spring Cave"

   centreline

   # Define the units that will be used.
   units compass degrees
   units clino degrees
   units length feet
   units depth feet
   units tape feet
   units altitude feet
   units dimensions feet

# A separate file contains all of the survey data.  Use multiple files 
as needed
   input CaveSpringCave-Surveydata.txt

   endcentreline


# Lower stream passage A survey
input 20161107/CaveSpringCave-LowerEntrance.th2
input 20221013/CaveSpringCave-A3-A7.th2
input 20221013/CaveSpringCave-A7-A17.th2
