Dear Bruce, I'm using the .xvi compiled with the option -layout-sketches on. This way, the .xvi file is not a simple vector drawing, with only the centerline, but a more complex one, with also the scanned images (which is a raster data) morphed to match the centerline (the vector data). Indeed I cannot scale or rotate any of the two components of the .xvi file (the vector, with the centerline, and the raster, with the scanned images) inside Xtherion. But I keep separate scrap file, one for morphing the scanned image, and one for drawing over the morphed image. This way I can modify anytime the first scrap, e.g. by adding more station points to get a better morphed image, I recompile and I get an .xvi which will be updated in every scrap that I'm using to draw the cave. I sent an archive with my data to the list on a previous message. You can look at and compile first the thconfig_xvi, than thconfig_pdf.

Hello Mihai I am intrigued that you are using both scanned images and xvi files in the same drawing file (as mentioned in your 23Nov message below). My friend and I were just discussing this and my assumption was that it would be an uncomfortable match if both types of image were used in the same scrap because we cannot scale or rotate background images within the XTherion interface (with respect to each other).
From your description below you seem to be using quite a different drawing strategy (in some respects) to what we use. If you are willing to share your dataset with the forum (if not too big) or by personal message, I would appreciate the learning. Thanks Bruce

It seems it will work if I add station points with the .xvi layer activated as background image. Initally I disabled the layer because of the grid, which I found quite annoying, and I kept only the morphed images. It seems that in this way the program didn't recorded well the coordinates of the points. Otherwise, with the .xvi grid and centerline visible, if I add a station point it recognizes its name automatically, and the coordinates are a little bit different, with lot of decimals.
For the moment it compiles fine, in both .pdf and .shp format.
Cheers, Mihai T.

Yes, the same problem occurs when I add several station points. But this happens only when I reeference the points to stations from the survey (witn -name ...). I think it's something related to my approach for morphing scanned images. I did like this: - first I started an empty .th2 file (named schita-c1_w.th2, _w stands for "warped") - I added a background image (a piece of the scanned sketch, CC01.jpeg), with Edit>Insert Image - I created a scrap and I selected the scketch as a background image, with the Insert button from the Scraps section in the control panel - I added several station points, referenced to the station from a survey, with -name ...@survey. From these stations it's only one that is georeferenced (with fix command, in the survey preamble) - then I compiled the map with -format .xvi - Now, I noticed that if I add the .xvi file to my first .th2 file, I get the image morphed, with the centerline on top of it, but displaced with respect to my initial station points added to the scrap. - That's why I a created a new .th2 file (schita_c1.th2), I added the .xvi file as a background image and I drew the wall. If I compile the map now (output esri .shp) everything goes fine, except that the .shp is not georeferenced. If I add to the scrap the station point that is georeferenced (fix) in the survey I get the error.
I put everything into the archive attached, if you have time to take a look, I would appreciate.

I put all my files in the .zip attached
