Adobe Illustrator CS5 - Illustrator

1. Adobe Illustrator CS5 - Illustrator Unit D:Creating Blends and Complex Artwork

2. 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

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

4. 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

5. Using the Divide Pathfinder FIGURE D-1: Positioning the five lines with the points on the star

6. Using the Divide Pathfinder FIGURE D-2: Selecting a piece of the divided star

7. Using the Divide Pathfinder FIGURE D-3: Finished artwork

8. 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

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

12. 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

15. 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

16. 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

19. 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

23. 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

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

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

26. 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

27. 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

28. 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

29. 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

30. Apply Arrowheads andDashes to Strokes FIGURE D-22: Stroke with arrowheads

32. 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

33. Designing Complex Layered Strokes FIGURE D-24: “Bull’s-eye” stroke with three layered strokes FIGURE D-25: “Film strip” stroke with three layered strokes
