There MUST be one or more point station in each scrap except section scraps.

So I had always assumed Martin, but NOT TRUE. As I mentioned in another post (it has not come through yet) I have just received a 5km long Therion project with nicely drawn map. There is not a single station in any of the scraps, and yet the scraps are aligned with the survey network. I plan to dissect it over the next few days to see how it works. There is an xvi with stations and left right masks, so maybe that does it?? Bruce
