Precision Drawing

Set Grid and Snap Values

The grid and snap features set up a framework that you can use as a guide while drawing.

■

Grid

displays a rectangular pattern of dots that extends over the area specified by the drawing

grid

limits

. The grid helps you align objects and visualize the distances between them. The grid does

not appear in the plotted drawing.

■

Snap

restricts the movement of the crosshairs to intervals that you have defined. When Snap is

on, the cursor seems to adhere, or “snap,” to an invisible grid. Snap is useful for specifying precise

points with the cursor.

Set Grid and Snap Spacing

The grid does not necessarily correspond to the current snap interval. You might set a wide grid

spacing to be used as a reference but maintain a closer snap spacing for accuracy in specifying points.

For example, you might set the grid spacing to 10 times the snap spacing in a metric drawing or 12

times the snap spacing in an imperial drawing.

Try it: Constrain the cursor with Snap

Start a new drawing.

Click the Snap button on the status bar.

Notice that the button changes color to indicate that Snap has been turned on.

Move the pointer around in the drawing area while Snap is turned on.

Notice that the cursor seems to adhere, or “snap,” to points at equal intervals in the drawing area.

Try it: Display a grid

Click the Grid button on the status bar.

Notice that the grid dots cover a limited area, the grid limits.

Turn Grid and Snap off.

If you zoom in or out, you might need to adjust grid spacing to be more appropriate for the new

magnification.
