USING ADOBE ILLUSTRATOR CS4
Painting
•
If you draw a bounding box around the artwork, make sure that the box is a rectangle, that it is the backmost object
of the tile, and that it is unfilled and unstroked. To have Illustrator use this bounding box for a brush pattern, make
sure that nothing protrudes from it.
Follow these additional guidelines when creating brush patterns:
•
When possible, confine artwork to an unpainted bounding box so that you can control how the pattern tiles.
•
Corner tiles must be square and have the same height as side tiles to align properly on the path. If you plan to use
corner tiles with your brush pattern, align objects in the corner tiles horizontally with objects in the side tiles so that
the patterns tile correctly.
•
Create special corner effects for brush patterns using corner tiles.

(Optional) To control the spacing between pattern elements or to clip out portions of the pattern, draw a pattern
bounding box (an unfilled rectangle) around the artwork you want to use as a pattern. Choose Object > Arrange >

Create seamless geometric patterns
1
Make sure that Smart Guides are turned on and that Snap To Point is selected in the View menu.

Select the geometric object. For precise positioning, position the Direct Selection tool on one of the object’s anchor
points.
3
Begin dragging the object vertically from one of its anchor points; then press Alt+Shift (Windows) or Option+Shift
(Mac
OS) to copy the object and constrain its movement.
4
When the copy of the object has snapped into place, release the mouse button and then release the keys.
5
Using the Group Selection tool, Shift-click to select both objects, and begin dragging the objects horizontally by one
of their anchor points; then press Alt+Shift (Windows) or Option+Shift (Mac
OS) to create a copy and constrain
the move.
