Now that I have played with this a bit more, I see that I get an error unless every scrap, map and map export projection declaration using those scraps has exactly the same projection bearing. I had thought it might be possible to generate a projected elevation map along a different bearing from that which the scraps were drawn on, but possibly not? Is it possible to generate projected elevations using extended elevation scraps? I am just trying to explore the options for producing projected elevation output from my source data so I can better understand how to draw up my initial elevation scale sketches on paper before trying to therionise them.

I could have clarified a bit more.

The problem that Footleg described when he tried to amend the example he sent (define the scraps as looking 090 deg) was because the scraps were looking to the east, but therion was trying to export non-existent scraps looking to the north. (By default therion will export just a centerline in this case, if there are no other errors).

 

The differentiation of elevation directions is necessary because often you may draw elevations of the cave from multiple directions (of course!).
