Thanks Bruce, I'll try that. In my case I had 3 scraps, each with 2 points. But the scrap I emailed the data from was in a separate .th2 file to the other two. The two scraps in the other .th2 file displayed fine. I am trying to import passage details drawn in another drawing package (via Inkscape) so I started with a few really simple scraps to test out my idea of how to do so. I assumed that I only needed two survey points in order to orientate and scale each scrap correctly. I'll try adding some more points (tomorrow, as I left the data on a computer at work) and see if that fixes the model.
