Re: [Therion] Distance between two survey station

Totally agree with Alastair :)

open the .3d File in survex

"Survex Aven" specifically.

select the two points

Select *one* point. Then hold your mouse over the second point.

H for horizontal distance - this is the one I suspect your looking for. L for length D for depth

H = horizontal component V = vertical component Dist = total distance in a straight vector (Oh how I wish it could also tell me "Distance along the survey legs between these points", so I could see how much caving I have to do to get there - pipe dream...)
