8 Using the rectangle tool , follow one of two methods:
•
For a fill pattern, draw a bounding box from the center point of the upper left object to
the center point of the lower right object.
•
For a brush pattern, draw a bounding box that surrounds the objects and coincides
with their outer boundaries. If the pattern is to be a corner tile, hold down Shift as you
drag to constrain the bounding box to a square. The bounding box should surround
the objects and coincide with their outer boundaries.

9 Paint the geometric objects the desired color.
10 Define the geometric objects as a pattern, following the procedure in
Constructing patterns with irregular textures
You can create an irregularly textured fill pattern that tiles seamlessly. Remember that fill
patterns clip any artwork outside the bounding box, whereas brush patterns do not. To
create an irregularly textured brush pattern, you should select and define as a pattern only
the textured artwork within the bounding box.

To create an irregular texture:
1 Make sure that View > Snap to Point has been selected.
2 Draw a bounding box. If you are creating a brush pattern, skip to step 13.
3 Draw the texture with the objects or lines that intersect only the left side of the
bounding rectangle.

4 Using the direct-selection tool, select the texture and the rectangle, and place the
pointer on the lower left corner of the rectangle.
