<DIV>I recently used Therion to produce a map for a short horizontal cave. The
cave is only a little over 100' long and the floor is almost level from one end
to the other. The "depth" information that Therion generated for the legend is 3
feet even though some of the passage in the cave is 5 feet high. I'm assuming
that therion uses the vertical difference between the highest station and the
lowest station to generate the depth number without regard to LRUD data, is
this correct? And does anybody have a suggestion for how I can easily
get the correct depth output onto my map? I can see how this could be a
significant issue if you had a cave with little vertical extent except for a
high dome. You would have to shoot a shot to a station at the top of the dome to
capture it's vertical extent in the legend data.</DIV>

<DIV>Also, I experimented with using "walls on" to see if it would get
Therion to use the LRUD data to determine depth. It didn't, but I found
that Therion is reading my LRUD data as meters instead of feet. I use the
command "units length feet" before the data but seems to only work for the tape
measurement. Am I missing something?</DIV>
<DIV> </DIV>
<DIV>Sorry if these questions are a little basic, but I've still got a lot to
learn about Therion. </DIV>
