I always leave the elevations to last.
Have just discovered that Topparser is not working for me when it comes to producing projected elevations.
Not sure if it is because;
1. Topparser is not using the declination from the top file to adjust bearings when it produces projected elevation xvi's, or 2. I have been too clever, and my habit of entering <decl correction> = declination + <therion plan rotation> in PocketTopo has got the better of me!
I suspect number 2 is most likely as Andrew seems to have done a pretty good job. Either way, unless a field for 'plan rotation' is added to Topparser, projected elevations are not going to work for me.
It is 1, well the declination is read in, however it is not used. Not caused me a problem as in uk it is only just over a degree. Just checked nz, I see 22 degrees will cause a problem, I will add it to the list. Is this not causing a problem with the plan as well? I will add this to the top of the list of things to fix.
As on the http://therion.speleo.sk/wiki/doku.php/paperless page I have been following this approach (that I came up with).
* PocketTopo stores the declination (and trip information like the date and the surveyors etc) that is set at the time a shot is received with that shot, and this association cannot be broken. If you subsequently change the declination (or other information), it only has effect for future shots. The declination is added to the compass bearing for the purpose of producing the sketch. So, if you enter an erroneous declination and take some shots, the drawing will be permanently skewed.
It is possible to change the actual trip for previous legs Hold down on a leg and click Trip... it will edit the trip information for that line and any others that are the same. Andrew
