To ability to export xvi as part of PDF output is long time on to-do list. The export of morphed sketches is part of exporting maps based on scraps or partial maps based on scraps, not exporting centerlines as defined in maps based on surveys. Martin

Hi, Bruce.
Thanks for the reply. The wiki pages you linked were one of the most helpful resources when I was trying to get this to work, along with Marco Corvi's "Therion by Examples".
I've tried selecting surveys, but when I do that I get an XVI file containing the centreline of the selected surveys, but no background sketches, even if I also select the map with the sketches in it. Changing the order of the select statements doesn't make any difference. I've also tried adding scrap outlines by drawing walls around the areas of interest in the th2 file in the vain hope that this would have some effect, but it did nothing. I've tried selecting scraps directly instead of maps, with the same result.
I think that this has the potential to be a really useful feature, but unfortunately its current behaviour regarding inclusion of centreline makes it all but unusable in large projects.
Best regards, Duncan.

Duncan I think your experience is more or less consistent with that here https://therion.speleo.sk/wiki/outputs#map_xvi_therion that I experimented with 4-5 years ago. One observation I made was that exporting a map to xvi actually produced something more akin to a model. In those pages I did not have any -sketch specified with the scraps, so I guess all Therion had to work with was the centreline (model). Although I don't think there is anything about on that wki page, I recall that xvi map exports are a bit 'scattergun' in that they do not respect the limits of the selected map. Maybe if a survey is selected rather than a map you may have better xvi control? Have a look at this table https://therion.speleo.sk/wiki/outputs#map_xvi_therion, it may provide some insight. It may no longer be current, and there may have been mistakes in it from the start. Any feedback welcome.

In my th2 file I've got scraps with -sketch specified, and stations placed to enable warping/morphing of these background images.
In th2 a map is defined (let's call it map_A) which includes the scraps I want.
Then in .thconfig:
select map_A
layout morph scale 1 500 grid bottom grid-size 100 100 100 m sketches on grid off endlayout
# Output plan in Therion pdf format export map \ -projection plan \ -format pdf\ -output map_A.pdf \ -layout morph
# Output plan in Therion xvi format export map \ -projection plan \ -format xvi\ -output map_A.xvi\ -layout morph
PDF output is as expected from the manual. It shows the background images attached to the scraps in the selected map, plus only the parts of the centreline that are used in those scraps. However if I change the export command to use XVI format, I get the background images and the centreline for the whole project, which contains over 20,000 stations. This is very difficult to use as it takes a long time for XTherion to load it, and then the area I'm interested in is tiny compared with the whole drawing area, so it requires quite a bit of zooming and scrolling to get there before I can start working.
Am I right in thinking that the XVI output should contain the same bits of centreline as appear in the PDF output, rather than the whole lot? Am I missing something?
Also: 'grid off' does not seem to affect the XVI output, which is why I've specified a fairly large grid size so that the grid isn't obscuring the sketches. I'd really like to be able to disable the grid in XVI completely.
Is there a way to achieve these two things?
Best regards,
Duncan. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
