Unit D:Creating Blends and Complex Artwork
Objectives
Upon completion of this unit, you should be able to: Use the Divide pathfinder Create compound paths Create complex patterns with compound
paths Blend objects Create a clockwise blend Create a clipping mask
Objectives
Use the Draw Inside drawing mode Apply arrowheads and dashes to strokes Design complex layered strokes
Using the Divide Pathfinder
Cuts objects where they overlap Result is multiple objects that can be
given individual fill and stroke colors• Example
– Divide two overlapping circles and you'll end up with three objects: overlapping area and the two areas that don’t overlap
Object can also be overlapped with just a line• Then use Divide pathfinder to slice the object
where the line overlaps the object
Using the Divide Pathfinder
FIGURE D-1: Positioning the five lines with the points on the star
Using the Divide Pathfinder
FIGURE D-2: Selecting a piece of the divided star

Creating Compound Paths
Compound paths: Occur when a single object is composed
of two or more paths Do not necessarily overlap
• However, the best example is when one path cuts a hole in another path
Command is on the Object menu
Creating Compound Paths
Letter A is created with two paths: Outer path Triangle within outer path
FIGURE D-4: Positioning the orange triangle

Creating Complex Patternswith Compound Paths
Once objects are compounded: Positive and negative spaces create
interesting geometrical patterns• Relationship of the compound paths is
maintained• Individual objects within can be moved to
create additional complex patterns• Useful when designing repetitive patterns

Blending Objects
Blend: Series of intermediate objects between
two objects• Every blend begins with a starting object and
an ending object
Blend tool: Offers options for choosing the number
of intermediate objects between the starting and ending objects
Blending Objects
Using blends: Both closed paths (e.g., a square) and
open paths (e.g., a line) can be used Most commonly used to create
interesting shape patterns, color blends, or both
A great way to add dimension
Spine: Horizontal line between the two original
objects

Creating a Clockwise Blend
Blends can be created between simple paths: Straight paths or curved paths
• Offers great flexibility • Can create interesting color effects
Clockwise blend: Colors blend like the hands of a clock
sweeping around a center point• No specific tool• Can only be made with blends between paths
Creating a Clockwise Blend

Creating a Clipping Mask
Clipping mask: Any object that you use to “clip” other
objects • Parts of the objects that are clipped are
visible • Parts that are not clipped are not visible
In a group of selected objects, the top object is always the clipping mask• Object being used as a clipping mask must
be a single object Command is on the Object menu
Creating a Clipping Mask
FIGURE D-17: Masking the blend with the starburst
FIGURE D-18: Masking the blend with five compounded circles
Creating a Clipping Mask
FIGURE D-19: Applying a stroke to the clipping mask
Using the Draw InsideDrawing Mode
Inside drawing mode Allows one object to be created inside
(within the perimeter) of another object• Essentially the same thing as creating a
clipping mask Two objects behave the same way any
two objects behave in a clipping set• Difference between Draw Inside drawing
mode and making a clipping mask: draw inside option can involve only two objects
Using the Draw InsideDrawing Mode
FIGURE D-20: Drawing the yellow ellipse inside the blue square
FIGURE D-21: Pasting the pink ellipse inside the outlines
Apply Arrowheads andDashes to Strokes
Stroke panel: Controls to create complex dashed strokes
• End caps determine the appearance at the ends of the path
Three end caps to choose from: • Butt Cap (default): blunt cap that ends at the
anchor points• Round Cap: creates an oval at the ends of the
path• Projecting Cap: extends the stroke past the
anchor points to a distance equal to one-half the point size of the stroke itself
Apply Arrowheads andDashes to Strokes
Arrowheads: Stroke panel also offers 39 arrowheads
that you can apply to the endpoints of a path
Scale option can be used to specify the size of the arrowhead
Apply Arrowheads andDashes to Strokes

Designing Complex Layered Strokes
Layered strokes: Produce some of the best illusions A number of different dashed effects can
be created with a single dashed stroke• Position of dashed and non-dashed strokes
on top of one another can create cool and eye-popping effects
Complex layered strokes: Very useful for borders on artwork and
for repeating patterns
