For cave-diving purposes, we added a custom line type to represent the
dive line with the cave. We can then change the properties of this if we
want to turn it on/off or change the style in one place.
Added this code to layout :
def l_u_caveline (expr P) =
T:=identity;
pickup PenB;
thdraw P withcolor (1, 0.5, 0);
enddef;
initsymbol("l_u_caveline");
We then drew the line on in each relevant scrap. Generally, it followed
the centre-line but it can be drawn in the centre of the passage instead.
example pdf here, the cave line is orange :

We also used custom areas to represent the water, using invisible
borders where necessary. You could maybe colour areas on the main route.

an additional thought just occoured to me:
If u draw a mainroute-line wouldn't it be possible for the coding-gurus
to get the length and maybe the altitude difference of that line type?
I would have thought the easier way would be a "flags" switch that could
do it for you. "flags mainroute". It wouldn't even be an estimate. Maybe
some of the Survex folks on this list could shed some light on how
feasible that would be. Might require a Survex modification though.
