I am not aware of that change - the Control Quality vs Survey or Mapping Quality and Unknown Quality have been in the TBC / BC-HCE product for a long time and they do not have any real direct correlation to Grid Only or Grid Coordinate settings as far as I know. The quality of a point is just an indication as to how accurately it has been established, with Control being the highest accuracy, followed by Survey, Mapping and Unknown in that order.
I do not believe that any change has been made to the Create Points command - I have requested many times to have the ability to set the Grid only or Grid Flag on the points created by this command like we can in many other commands, however the Geospatial Team have resisted that request so far so the change has not been made.
Let me know if you have read about some change somewhere that I may have missed, as I am not sure what your reference is here Ben.
Thanks
