[Therion] Multiple elevation maps

10 Nov 2014

      Hello everyone -

I am working on a map where the cave makes a T-junction.  I have an elevation 
working for the passage from the entrance to the junction.  Now I want to make 
a NEW elevation map for each arm of the T.  

I think the secret I am missing is how to specify the scraps to be included in 
a specific layout.  I included sections of the thconfig and main.th file below.  

The output I get is two identical elevation maps which include all of the 
elevation scraps.  What I want is two (or more) elevation maps each of which 
includes only a few scraps.

The main map will then include each of the elevation maps as "map-image" 
lines.  These will go in different positions so they match up to the portion of 
the plan they illustrate.

Looking through the Therion Book, I see that scraps can have an index (page 
20).  Do I need to assign different indexes to the scraps depending on which 
elevation they go with?

Thanks - Bill Gee
