Hi Bruce - Thanks for the hint about "select". That was the missing
ingredient. I was looking all over the map where offsets work - in the
.th file! - and missed seeing that in the thconfig file. It's been a
year since I did any of this, and that step just got missed.
The good news is the offset is working. However, it did some other
stuff that I need to get changed. Attached to this message are the .th
and thconfig files I am using. The resulting map can be downloaded from
https://campercaver.net.MiscFiles/CaveSpringCave-Print.pdf
This map is very much "in progress". I have drawn walls for everything
that has been sketched and now I am filling details. There is survey
line that has not been sketched, and much more survey to be done.
On the map you find two entrances, both on the west end of the cave.
The big entrance (the A survey) is about 30 vertical feet below the
smaller entrance (the U survey), and the passage from it runs under
everything else. There is a pit where it joins the upper main passage.
I want to draw the A survey -under- the U survey. Before I added the
"select" statement to thconfig, it was working. Now it appears to draw
the A survey on top of the U survey.
There is another passage in the cave that crosses the main passage.
This is the X-Y survey. It is above the U survey. When I did not have
a select statement, it was drawn with correct shading at the
intersection. Now it does not have that.
I changed the .th file so that the map for the lower entrance does not
have either offset or "below". That did nothing but change its
background color. It still is shaded so as to appear above the U survey.
As a side comment, I found that whenever I use "above" or "below" on a
submap, I must also include the offset [0 0 ft], else therion will not
compile the map.
Thanks!

Hi Bill
Does your previous project still compile and create an offset map?
In your thconfig you should make sure you have some things:
* maps on # [on] off ## Setting maps to off disables all previews and
offsets, and only scraps from the selected maps are output. Survey
centrelines included as part of a map are not output.
* maps-offset on # [on] off ## Setting maps-offset to off disables all
offsets. Maps-offset has no meaning or effect if maps off is also
chosen.
* select MainPlan #otherwise the offsets defined in MainPlan will not
be exported
I’m also not sure what the effect of:
A-Survey@CaveSpringCave [0 0 ft] below
will be.
Zero offsets are not something I remember trying, but it is probably
better not to do this while you are trying to debug your project.
Regards
Bruce

Subject: [Therion] Cannot get offset maps to work
Hello everyone - Most of my recent questions to this list have generated
exactly /dev/null for response. I hope this one gets something.
I am trying to build a map where one section of underlying passage is
drawn offset from the main map. I have done this before and it worked.
This time therion is completely ignoring the offset parameters. What am
I doing wrong?
The portion that I want to offset does get drawn, and it is drawn below
as I specified. It just does not get drawn offset.
I tried taking the offset out of the list. Therion complained about
that. I tried offsetting the other two partial maps, and that does not
work.
The last time I compiled a map with an offset, I was using therion 6.1.8
on Fedora 38. Now I have 6.2.1+dev on Fedora 41. Did something change
between those two versions that affects how this feature works?
I attached the .th file to this message.
Thanks!
