... very sorry about that. In fact I think you are the first user to specifically ask about it. I'm working on a bit of tutorial for you, but it may be a while before it's ready. I started with the 25" scan of Corfe Castle which Neil Berrington uploaded in this topic: topic 1046 and loaded it as a normal track plan picture shape: 2_171214_340000000.png If anyone wants to try it, the original image file in the Gallery is 300dpi and 1:2500 scale: gallery/46/original/46_131232_230000000.png Thanks Neil. The intention was to fit it into the corner of a room, and this is the result, now ready to have the remaining tracks aligned over it: 2_171214_340000001.png 2_171214_350000002.png This is a 2-stage process, using the wrapping function twice. First to straighten out the original running line, and then to wrap it onto the corner curve. The process is not difficult, but also not immediately obvious, so I shall have to prepare a sequence of detailed screenshots. I hope to have it done soon ...
