Hello A strange rotation was encountered relative to the grid, when playing with cs OSGB:SN and cs EPSG:27700
In the end this was tracked down to the fact that the 300000 400000, was still within all the fixes, which is wrong, but this put it well outside the SN area, and hence the rotation. (or that is what we think) Which lead me to the thought, maybe therion should warn, but continue if it finds an co-ordinate outside the area covered by the cs selected? Not sure if this is possible (easy) to do, but in this case would have saved lots of head scratching. Andrew
