Hi JP Try "units imperial". Best, Torsten McLendonJP@aol.com hat am 27. Juni 2012 um 14:23 geschrieben:
Graham, I've got the centerline and LRUD data all together in the same block, as in "data normal station left right up down newline length compass clino" and immediately before it "units length feet" but it still treats my input numbers at meters instead of feet (for the LRUD). Olly's suggestion to use "units left right up down feet" works perfectly to get Therion to treat the numbers as feet.
Thanks, JP

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?
Can I assume that you have separate blocks of data for the centreline and the LRUD? If so then you need to enter the "units length feet" line again after the "data dimensions station left right up down" line.
Alternatively just take all your measurements in metres ;-)
You are right, however, that Therion determines depth by the difference between the highest and lowest stations. It is difficult to see how else it would work. It is a trivial matter to mark your highest and lowest points as stations.

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.
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.

Sorry if these questions are a little basic, but I've still got a lot to learn about Therion.
Much thanks, JP McLendon
