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.

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.
