Raster Snap is active only when you are in a command and are being prompted
for a point.

1 Click Click Image  ➤  Raster Snap..

2 On the 

 (page 309) tab, under the Snap Modes section, select

the snap mode or modes you want to use.

If you choose more than one snap mode, then the cursor snaps to the
closest of the possible snap points. For more information, see 

(page 238).

3 In the 

 (page 398) box, type the desired size (up to 300 pixels)

for the snap window. The larger you make the snap window, the longer
Raster Design takes to search for points.

NOTE Because the snap window is measured in image pixels, not screen
pixels, the size of the snap window changes with the zoom level.
