Graphics – Grid Display and Grid/Cursor Snapping

There are three user-alterable conditions dealing with grid points on the screen:

 

Grid display, which controls the display of grid points;
Grid snapping, in which the cursor moves only between grid points;
Cursor snapping, in which the cursor snaps to a grid point only when that point is digitized. Grid snapping must be turned on for cursor snapping to occur.
