I am not sure if all your elevations have the same projection (ie extended), or if you are using different projections or each arm of the Tee (for example 000 deg looking at the top arm of the Tee, and 270 deg looking at the vertical of the Tee).

However regardless, defining maps as Martin suggests is the path you should take to gaining control.

The only reason I have found to use projection indexes is where you intentionally draw scraps of the same projection that are incompatible in some way, such that you would never want to mix those scraps in the same export;

– ie you draw say two plans optimised for very different scales, and you would never mix the ‘big scale’ version with the ‘small scale’ version, or more credibly,

– you have two versions of an extended elevation centreline (different extend left/right etc) for the same survey legs and so these will need quite different and incompatible scraps to be drawn.

Therion treats each projection index as a completely different projection, so you cannot mix projections with differing indexes any more than you can mix plan and elevation within the same export statement.

Subject: [Therion] Multiple elevation maps

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
