More precisely equivalent to Therion's 'extend reverse'.

Yes, I think this might be something I will end up relying on, because
it is much more readable, and understandable. And on top of that, you

Pretty sure this is the way it is. Which is why I tend to use extend

In the case of what you said,
Hi Tarquin,
I am afraid, I do not understand your problem.
If extend algorithm follows stations in order 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8
- 9 and you specify
extend vertical 3
extend right 8
Then stations 3,4,5,6,7 should be placed vertical and 8,9 on the right. I
have tested it and in my example, i
Stacho,
I am wondering if there is a fault in all the other "extend" options,
rather than this problem being specific to "extend ignore".
extend vertical 3 # everything after station *2* is vertical
extend right 8 # everything after station *7* is extended to the right
It seems like your "extend
exactly what is
going on, so that I can then make good decisions.

Brilliant! Thanks Stacho :)
I will add it to my wiki article. (And I have no doubt that Bruce will
also add it to his.)

I have now added a new article, with details of the investigation:

Because it uses a load of images, it was nicer to have it as a separate
article, rather
you isolate the particular leg that you want? A textual debug might help find
the answer.

Thanks so much for this explanation! Suddenly everything makes sense,

Normally,
extend ignore 6
should do the job. But there was a bug in the code, so it did not work as
intended.
It should be fixed now in the latest commit. If some of you have more
complex entended elevation projects, could you please check, whether this
change does not introduce new errors?

Hi Bruce,

Thanks for that detailed explanation!
The main things that threw me were:
1. That Therion is stepping *backwards* along the oxbow - in the
direction of the cave passage from the "start" instead of in the
direction that it is surveyed. This means

You are right. It is very strange it break centreline in station 2 and not in
station 5 or 6.

Bruce, that was some black magic. I don't quite understand why asking it
to ignore a leg then changing your mind and asking it to draw it anyway,
would cause it to then split it at the point you want. I wonder if I
