Grid Display and Grid/Cursor Snapping

Description

There are three conditions dealing with the display and snapping of grid points in a graphics window:

 

1.Grid Display, in which grid points are displayed as points or lines on the graphics window;
2.Grid Snapping, in which the grid is turned on and cursor behavior depends on the Cursor Snap setting;
3.Cursor Snapping, which determines whether to force the cursor to move only between grid points or to snap to a grid when a point is digitized.
