Hi Bruce and Martin - Very nice! This is exactly what I was looking for. The "secret" is how the select statements work, and then to have a select before each export. I will apply this to the real cave map I am working on and report back results. There is a new question ... What is the effect of specifying the degree angle of the view for "-proj elevation"? The profiles for the real cave I am working on were sketched along the survey line. That means they bend and twist as the survey line bends. In this case the survey line is very close to running down the center of the cave, but that is not always the case. One leg from the T-Junction has a "dog leg" bend in it. At one station it goes from north to almost east for about 70 feet, then it turns back to almost straight north. The profile sketches follow the centerline and so make the same twist. Since every profile sketch has two survey stations (or more), Therion can morph the sketch to the data. If a view angle is specified, does it mean that some sections of the profile will be morphed more than others? Many thanks for all your help!

The attached files demonstrate what I think you were describing in your original message. All of the changes I made to your files have the tag #B20141112 added to them.
I have modified each elevation map to use a different projection. Of course it is ridiculous with this particular example, being essentially straight, but it is the sort of thing one might do for a Tee shaped cave as you originally described.
I had to change the projection of each elevation scrap, and this is not something you would usually do after it has been drawn - of course the shape of a scrap depends very much on the projection, and to change the projection later on will usually render it meaningless (although Therion can pull off some amazing morphing).
I added debug all to label the scraps, stations and observe the morphing.
I also took the opportunity to test the transparent background that I was having trouble with in my datasets - it works!
Regards
Bruce

Hi Bill
I think I see your problem. I will potter around with the example you sent
to demonstrate what I think you want, but maybe not tonight.
For now, you can avoid the 'object not found' error by double clicking on
the survey or map item on the right-hand side of XTherion. For example it
places...
select AllElevations.map@PracticeCave
...at the cursor position in the th-config file.
And, if you select multiple maps of one projection, they will all be used in
the export for that projection.
-Plan is a projection
-Extended is a projection (developed or straightened out elevation) see
http://therion.speleo.sk/wiki/doku.php/faq#projections_plan_elevation_extend
ed_and_none
-Elevation is a default for [elevation 000 deg] ie 'looking north'. So
assuming there are 360 degrees in a circle there are 360 different elevation
projections.
If all your elevations have the same projection, all the elevation maps will
end up in the same pdf (unless you modify the th-config between runs or use
multiple th-configs as Rowena suggests).
I will modify your example to demonstrate using two elevation projections
(without resorting to indexes).
