Using the grid, snap alignment, cursor restriction, and dynamic input

Grid and snap settings are effective tools to use in your drawing to ensure accuracy. Although many users find it convenient to match grid points to snap settings, they are independent of each other and should not be confused. Grid points are for visual reference only; they do not affect your drawing and they do not print. Snap points are, by themselves, not visible; however, when set, they constrain the creation of new entities.

In addition, the cursor can be restricted to move orthogonally only or guides can display on the screen automatically at specified polar angle increments.
