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.
