The Edit Grid definition tool is used to modify an
existing grid or graticule definition. When selected, the Edit Grid Definition
dialog opens to allow modification of the following grid parameters: general
settings, labels, tick marks, cross ticks, units, intervals and grid lines.
Note: The scale and the
coordinate system of a grid or graticule definition cannot be modified. If you
need to change these parameters, either create a new definition from scratch or
use the duplicate tool.
