Perhaps this is time to air my observation that, although the pdf files are layered, the layering adopted does not appear to be as useful as it could be. This may be however, due to my limited resources (experience, mental capacity and software) when it comes to manipulating pdf files.
The Map pdf's I create tend to have three layers, - one named after the title of the map that contains all the cave centreline and drawing, - one named surface, that contains all the cave sketches and surface images, and - an unnamed background layer that contains the grid, map-images and the header/legend. The Atlas I think are not layered. I have not branched much into chapters or multiple maps in the same output, but they may have some manifestation in the layering that I have not yet noticed. Unless there is a fundamental reason why it can not be done, I would have thought that extensive subdivision and hierarchy of layers would be advantageous. If this were implemented then I imagine that the person viewing the pdf could choose layers so that they could view say, surface only, or cave only, or cave with no text, or cave with no text and no speleothems and no area fills, or centrelines only, or centrelines and station names etc. One output - multiple presentations. (Large file size I guess) Just a thought for the future direction... Any way, current frustration. I'd like to be able to see my cave drawing and scanned cave images overlaid on top of my surface image, but currently this is not possible from Therion. Multiple runs and some post processing is required. I would tend to put the sketches on their own layer, separate to the surface and separate to the drawings (scraps) Not particularly urgent, but I would see this as important in the medium term - one plus years (??) say. I have a project in mind that will require at least the separation of surface and images.

Well, currently the background sketches are drawn as surface images - so surface top|bottom|off should affect it, but I am not sure if hide/show surface-centerline will. I need to check this. It is planned to be placed into same PDF layer as scraps are, but it will take some time, until it will be implemented. Do you have some problem with it?
