I see, I assumed what the camera sees was correct. So when the zone was drawn completely in the wrong place I didn't realise it
was in the correct position.
Because the structure I am trying to place the zone edges along is wider at the base and curved they [the zone points] look like the points are out by miles, but I suppose I'll just have to try doing it looking only at the co-ordinates.
If they were able to stay in the same plane and not snap to the terrain it would be a simple matter to line the visible height of the zone with the tallest entity and then move the points maxing them a lot easier to place by sight (in this instance).
I think what would aid this, would be if the zone borders could be shown as 3D (like the cubes in Classic), and then it would be easy to see where the wall of the zone was irrespective of the full xyz of the points, rather than as a mostly 2D plane.
