Adobe Illustrator CS 5 - Illustrator Unit D: Creating Blends and Complex Artwork

Objectives Upon completion of this unit, you should be able to: Ø Use the Divide pathfinder Ø Create compound paths Ø Create complex patterns with compound paths Ø Blend objects Ø Create a clockwise blend Ø Create a clipping mask

Objectives Ø Use the Draw Inside drawing mode Ø Apply arrowheads and dashes to strokes Ø Design complex layered strokes

Using the Divide Pathfinder Cuts objects where they overlap Ø Result is multiple objects that can be given individual fill and stroke colors • Example – Divide two overlapping circles creates three objects Ø Object can also be overlapped with 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

Using the Divide Pathfinder FIGURE D-3: Finished artwork

Creating Compound Paths Compound paths: Ø Occur when a single object is composed of two or more paths Ø Do not necessarily overlap • However, the best example is when one path cuts a hole in another path Ø Object menu | Compound Path | Make

Creating Compound Paths Letter A is created with two paths: Ø Outer path Ø Triangle within outer path FIGURE D-4: Positioning the orange triangle

Creating Compound Paths FIGURE D-5: Creating a compound path with three objects

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

Creating Complex Patterns with Compound Paths FIGURE D-7: A simple pattern created with compound paths

Blending Objects Blend: Ø Series of intermediate objects between two objects • Every blend begins with a starting object and an ending object Blend tool: Ø Offers options for choosing the number of intermediate objects between the starting and ending objects

Blending Objects Using blends: Ø Both closed paths (e. g. , a square) and open paths (e. g. , a line) can be blended Ø Commonly used to create interesting shape patterns, color blends, or both Ø A great way to add dimension Spine: Ø Horizontal line between the two original objects

Blending Objects FIGURE D-13: Blending four stars

Creating a Clockwise Blends can be created between simple paths: Ø Straight paths or curved paths • Offers great flexibility • Can create interesting color effects Clockwise blend: Ø Colors blend like the hands of a clock sweeping around a center point • Can only be made with blends between paths

Creating a Clipping Mask Clipping mask: Ø An object used to “clip” other objects • Parts of the objects that are clipped are visible • Parts that are not clipped are not visible Ø 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 Ø Object menu | Clipping Mask | Make

Creating a Clipping Mask FIGURE D-17: Masking the blend FIGURE D-18: Masking the blend with the starburst with five compounded circles

Creating a Clipping Mask FIGURE D-19: Applying a stroke to the clipping mask

Using the Draw Inside Drawing Mode Inside drawing mode Ø Allows one object to be created inside (within the perimeter) of another object • Essentially the same thing as creating a clipping mask Ø Objects behave the same way as 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 Inside Drawing Mode FIGURE D-20: Drawing the yellow ellipse inside the blue square FIGURE D-21: Pasting the pink ellipse inside the outlines

Changing the Appearance of Strokes Stroke panel – End Caps Ø End caps determine the appearance at the ends of the path Ø 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 and Dashes to Strokes FIGURE D-23: Dotted stroke with round caps

Changing the Appearance of Strokes Stroke panel – Dashed Strokes Ø Dashes/Dots can be placed onto a path Length of 1 st Dash Stroke Space after 1 st Dash Stroke

Changing the Appearance of Strokes Stroke Panel - Arrowheads Ø Stroke panel also offers 39 arrowheads that you can apply to the endpoints of a path Ø Scale option can be used to specify the size of the arrowhead

Changing the Appearance of Strokes FIGURE D-22: Stroke with arrowheads

Designing Complex Layered Strokes Layered strokes: Ø Produce some of the best illusions Ø A number of different dashed effects can be created using 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: Ø Very useful for borders on artwork and for repeating patterns
