I have not yet drawn a wet cave, but I've been experimenting with
line border:presumed -clip off
for flood levels. You

I'll add the gpsvisualizer to the Therion wiki, as it looks like a good way
to get a smoothed ground profile over a cave centreline. Just so I'm clear,
did you just upload your therion generated kml file here?

Yes, I used the 'model' version of the .kml file, with the x, y
centreline
Martin,
Picking points from GoogleEarth works very well. Thank you for the
suggestion. I found a very useful tool here :
http://www.gpsvisualizer.com/elevation
By simply importing the .kml file of the cave centreline data
(lat-long), this online tool will create a list of coordinates
You may read altitudes of points from GoogleEarth. A macro may help. Grey and
white PDF you may create from dummy scrap and then crop the final PDF file.

I'll be interested to see if anyone has managed to create a ground line as
you describe. I assume it is not possible to make it a boundary for the
background colour.
I have just tried taking a 3d gps trail with 2m resolution and then
including it as a survey line and this can be included
[re-sent due to email address error]
I am looking for some advice on the best way to add the profile of the
ground surface to a cave elevation (for pdf export). Apologies if this
is in the book and I've missed it.
Currently, I have the background colour as a light grey, with cave the
