[Therion] Multiple caves on one map with an offset

[Bruce Mutton]

As Martin suggested, you just need to define a top-level map, and select
that for output.

 

Here is a snip of a top level map that is part of a set of maps I have used
to highlight chronology in atlas outputs.

Your relationship of scraps and maps to surveys is different to what I use,
so the namespace relationship will be different.

The first time, you may need to figure it out yourself, but once you have
done that you can compile your project, then in the compiler window, double
click on the component map to select it with its correct path.

Hi Bruce -

 

Yes, I am now referring to PDF outputs. It has not bothered me enough to
chase down the solution. I am pretty sure there is some combination of map
and select statements that will do the trick. The last time I thought much
about this, the problem I came up with was how to tell the BigCavernRanch.th
file the names of the various maps in the other .th files. I don't know how
the scope of the name spaces works in this kind of configuration.

 

The issue will probably become more annoying in a few weeks. We are planning
a major survey expedition to these caves for Nov 10-11, and I will have a
lot of new data to work with. The passage that I want to offset is
particularly difficult, less than 12 inches high for most of its known
length, so there are very few people who are willing to do survey in there.
At least it is in dry clay! No water to deal with.

 

The old maps you have may not include this passage. It takes off from the
top of Texas Dome, which is in the far north part of Allie Spring Cave. We
call the passage "Top of Texas". It runs pretty much directly above other
passages. Even with transparency it makes for a rather confused presentation
unless it is offset to the side.
