I’m digging this topic since I’m running in a similar issue. Would that be possible to have for the points with the option “altitude" something like :

640 [-30], where 640 would be the altitude and -30 the depth ?

Thanks,

Phil

Hi all,

I think I have found a trick. The other Xavier led me to the right tracks, thanks a lot !

Finally, this is quite simple with the point altitude, and no need to change anything inside the :
- If we use the point altitude only with the option -align, we get the altitude
- If we use the point altitude with the options -align and -value [-1004 m] where 1004 is the altitude of the main entrance, we print the depth only for that point (Do not forget the "-" before the altitude of the main entrance), and thus, we do not erase the classic point altitude.

The only (small) limits are :
If the main entrance changes, we need to manually update ALL the points that print the depth. But that should not be be everyday, and not a big issue to do that.
the symbology of the two points is the same. I will have a look for a way to modify that and let you know if I find a trick (If I copy the code of the point Altitude, and call it p_u_depth(expr pos, R, S, A), it crashes...).

Cheers,

Xav
