Hi All. _ Have solved the mystery - and I think its a bug in the software. If you start with a new sheet/drawing then the coordinates displayed by the text tool are correct in relation to the reference point (Origen) [0,0,0]. However if you change the axis at all then the coordinates displayed by the text tool are still relative to the original axis and Origen. The only point in space that is updated to the new Origen is 0,0,0 (or any combination). I found this be creating some boxes and moving then to points in space with the MOVE[x,y,z]. This worked perfectly until I changed the Origen - then s--t happened. Thanks for reading the post.
