[Therion] Projected Elevation

[Andrew Atkinson]

I have a couple of caves (probably more) that could really do with a
projected elevation, rather than extended.

so I set off trying to do it. I started with one looking towards 90
degrees, but did not get any walls and the centreline was always
projected looking north.

Eventually found this

Which indicates that in atlas this is all that is implemented. I assume
it is the same for map?

So I moved onto the cave that has a projection looking north. At least
the centreline now looks right, but I am not getting any walls. Should I
be, or is this not implemented either?

Is the implementation of Elevation likely to happen, or should I start
to look for another way?
