Footleg May need to include your th and th2 files to be more specific.
Couple of likely issues. 1. Firstly check that the direction of the projection is the direction in which you are looking. Ie on the elevation the direction will then be 'into the page'. If you don't specify a direction then Therion assumes it is north. I would guess you have some scraps/maps with differing projection directions, and so naturally they are different projections. If you have for example 3 different projection directions, then therion will make three elevations (if you ask to export them). Look in the log file or Xtherion compiler map structure pane for clues. 2. Make sure every scrap and map you want to include in this elevation has the same projection. Many versions ago I found that Therion assumes 0 is not the same as 000 and 20 is not the same as 020. So I always use 3 digit integers these days. 3. Differing coordinate systems. If you for example use a different thconfig for the main map production and test plots of parts of the cave you might be using different coordinate systems or declinations each time. This will really screw up the elevations where passage is almost in the same direction as the projection, because Therion will morph as much as required. In this situation it often turns into a real mess.

I've tried searching the wiki and Therion book to find an answer to this, but it does not seem to feature anywhere. Not even in any examples I can find. I am trying to draw a simple cave with a 20m vertical entrance shaft, and a couple of chambers down a slope at the bottom. I've drawn an elevation scrap for one of these chambers and the shaft. But when I generate an elevation map using this scrap the shaft looks fine, but the chamber wall is a mess. So I concluded it is not projecting the elevation along the bearing I would like. The Therion book showed me I can put a bearing on the scrap type. So I tried elevation 90. Now my shaft is no longer appearing anywhere near vertical in the elevation PDF and the chamber. Can anyone help me please? Screenshot of scrap, and pdfs with default elevation map and elevation 90 settings attached.
