A mucdh smaller problem than my last one ... Stark Caverns has several
places with stairways. I am using the line type "steps" to draw them
in. Three issues:
1) One of the stairways is wider than long, and only three steps. When
Therion draws that, it places it sideways. Is there a way to tell
Therion how to orient the steps?
Here is the definition from the th2 file:
line steps -close on -attr c 3
1558.0 -1203.5
1593.75 -1206.75
1581.75 -1158.75
1553.75 -1167.0
1558.0 -1203.5
endline
This can be seen on the map at
https://campercaver.net/MiscFiles/StarkCavernsNoCenter-1.pdf
Find the Onyx Circle. There is an arrow calling out a ceiling
waterfall. Move west from the arrowhead about 5 scale feet to see this
set of steps.
There is another stairway very close by which has more steps. That one
is oriented correctly.
Related question - Is there a way to indicate which end of the stairway
is down?
2) I originally defined this stairway using a curved line on one side.
When Therion compiled the map it gave an error about "illegal steps
definition". The only way I found to fix that was to draw it again
using only straight lines.
I know Therion can have curved lines in a stairway because there are
some others in this map where I did that. Is this a case where Therion
requires straight lines for the top and bottom, but can have curved
lines for the sides? If so, then changing the orientation as in problem
one should fix this.
3) For future versions of Therion - The Therion Book does not have any
documentation about the "-attr c #" option for the steps line type.
This needs to be added. Also a note about curved vs. straight lines,
and how to change orientation.
Thanks!

Hello everyone - I am having a problem getting Therion to understand how
to join several scraps to make a large room. The working map is at
https://campercaver.net/MiscFiles/StarkCavernsNoCenter.pdf
Take a look at the east part of the map in an area called Grand Canyon.
This is really one large room, though we did not realize that when we
started sketching several years ago. Now I have at least three
different pieces of sketch to try and fit together.
As you can see, there is a large triangle in the center which Therion
thinks is not cave. There are also some part which are outside the
cave, but are considered by Therion to be inside.
All of the joins in here are using line-to-line. I named the lines,
then created "join" statements specifying the two lines and which points
on those lines to join. Therion is happy with that, and the wall that
it draws is a fair depiction of the area. The problem is that much of
the interior is getting lost.
I have not tried to use plain joins of the scraps - joins which do not
specify the lines. I suspect that would not change much.
I have already drawn some of this area three times. It is
extraordinarily complicated due to multiple levels, especially along the
east side. We thought for a long time that the east side was separate
passages, but it is really just a complicated pile of big breakdown blocks.
I really REALLY do not want to go back and make one huge sketch of the
entire room. That would take several days.
What can I do to convince Therion where the cave really is? Can I put
in some invisible walls (subtype hidden)?
Thanks!
