Re: [Therion] Depth seems to be including surface legs

Hmm, but it looks to me, that scale is only up to altitude 481m​, which is
altitude of entrance. No surface centerline taken into account.

Re: [Therion] Depth seems to be including surface legs

Agreed - which makes it all the stranger that the indicated depth on the 
plan legend is 13m - which includes the surface centerlines.

Yes the entrance is marked.
I've attached the Aven view with entrances highlighted (Therion
generated 3D file).
Note that the surface legs have been excluded from the Aven
presentation.

Entrance was declared as follows:
cs OSGB:XX
fix 21 X X 480   # Tweaked to match Google Earth
station 21 "Old Mine" entrance
Coordinates blanked out at this time.

We surveyed the surface above an old mine to get a feel for how

roof is.
See attached Loch screenshot.

Unfortunately, the surface legs are being included in the Depth
value
displayed on the Plan PDF (see attached).
Displayed value is 13m, it should be about 8m. 13m is the maximum
vertical extent of all our survey legs.

The centerline data for the surface legs has been flagged as "flags
surface".
These have been correctly omitted from the cave length, and cave
length
is updated when the surface flag is commented out. However, the
vertical
range does not alter when the surface flag is toggled.

I expected cave depth to be the maximum vertical range of the
underground data.
Hope someone can set me straight :)
