[Therion] Wall visibility affecting lox model

[Footleg]

So you spotted that I missed off a line showing part of my chimney.
I've added that now. I've also removed all my duplicated invisible
wall lines and just set the option '-outline out' for the chimney
lines which are also walls in my sketch. This works great and both my
PDF and lox model look like I wanted them to.

Martin raised a couple of questions about my drawing of chimney and
pits. I follow the point about the wall of the chimney which is also
the passage wall not needing to be drawn as a chimney line
(technically there is no undercut on the ceiling so I realise that I
should not use a chimney or ceil step line there. But I always thought
it made it clearer that there was an aven above the general passage
roof at these places if I encircle the entire aven with ceil step
lines. In effect I am using the ceiling step line to indicate that the
ceiling inside that line is higher than the general ceiling height of
the passage. What do other people do? I've attached another screen
grab from my PDF. This also shows the pit as it is intended with the
scrap included which covered the floor of the pit. Then you can see
that the pit is no longer transparent on the PDF.
