[Therion] Fix station point using only 2D

[Henry.Bennett at dell.com]

Assuming that you've got another fix for the entrance then you should be able to get the height for the end station.  Just look at the .3d file.  That will give you the relative altitude at the end - just use that.

Hi all,

How to 'fix' the survey station point (to morph the cave plan) having only 2D coordinates?

Using the radiolocation we get (with quite good accuracy) the station point position which is about 150m beyond the estimated location we get from surveying. So now I wanted to use this position to make a correction to the main polygon. But the 'fix' command need a 3D coords so how should I do that (no, there is no point to measure the depth by radiolocation by some reasons).

Thanks in an advice,
Adam
