Home ribbon >> Snap >> Snap >> Grid Snapping Parameters.
In the Command toolbar, run the command set-snap-grid-parameters or use the quick keys 'gs'.

The Snapping Grid screen is used to define the snapping grid's origin and interval parameters. Define the XYZ increment values and origin. These settings are used when digitizing new or, editing existing data, e.g. points, strings and wireframes.

The Snap to Grid mode must be active for these settings to be of any use.
