DRAW
MYGRAPHICSLAB: ADOBE ILLUSTRATOR CS6
Copyright © 2013 MyGraphicsLab / Pearson Education
IN THIS LESSON, YOU WILL LEARN TO:
Set Pen tool stroke and fill Draw line segments with the Pen tool Draw curves with the Pen tool Create open and closed paths with the Pen tool Add and delete anchor points Convert anchor points Move and align anchor points and segments with the
Direct Selection tool Use smart guides Draw with the Pencil and Eraser tools

THE POWER OF THE PEN TOOL
When you draw in Illustrator, you generate anchor points(pivot points for paths) and paths (the line segmentsbetween anchors)
Two ways to generate anchor points Draw with a shape tool, the Pencil tool, or the Line tool
When you use this technique, you appear to be drawing paths, butIllustrator is generating anchor points for you
Draw with the Pen toolWhen you use this technique, you are consciously defining anchor
points as you draw
Two ways to use the Pen tools Draw with the Pen tool Use the assorted pen tools (Add Anchor Point, Delete
Anchor Point, Convert Anchor Point) to adjust artworkgenerated with shapes and other tools

Defining the stroke thickness for a selected object
SET PEN TOOL STROKES
Stroke color can bedefined in the Toolspanel; more attributescan be defined in theControl panel
In Tools panel Assign a color, or set
Stroke to None In the Control panel
Color / alternativecolors
Thickness Variable width profile Brush definition
Order of operations(when to set stroke) Before drawing: Define
stroke, draw path After drawing: Select
path, define stroke

Selecting a fill from the Control panel
SET PEN TOOL FILLS
In the Tools panel Assign a color, or set
Fill to None In the Control panel
Set color /alternative colors
Order of operations(when to apply fills) Before drawing:
Define fill, draw path After drawing: Select
object, define fill

Choosing a fill from the Beach swatch panel
MORE ON STROKES AND FILLS
There are almost limitlessattributes and effects thatcan be applied to strokesand fills
Fine-tuning strokes Caps, joins, and style
defined in the Strokespanel
Stroke colors fine-tuned inthe Color panel
Fine-tuning fills Graphic styles library
presents dozens of groupsof combinations of effects
Swatch libraries organizecolors and fills

Generating a curved anchor point with the Pen tool
DRAW LINE SEGMENTS WITH THE PEN TOOL
To generate straight angleanchor points Rather than click and drag,
click and click to defineanchor points
Constrain angles to 45°increments by holding downthe Shift key as you click
To generate curved anchorpoints Click, then click and drag, to
define curve of the vectordefined by the anchor points
Constrain control handlesthat define the curve to 45°increments by holding downthe Shift key as you click

Applying a fill to an open path
DRAW OPEN PATHS WITH THE PEN TOOL
An open path has differentfirst and last anchor points(not “airtight”)
Open paths can have fills Create anchors and
segments until you have thedesired open shape
To complete the shape,select another tool or pressCtrl (Windows) or Command(Mac) Pen tool remains active until
you close the path or selectanother tool
Copyright © 2013 MyGraphicsLab / Pearson Education
Closing an open path
DRAW CLOSED PATHS WITH THE PEN TOOL
Closed paths have the samefirst and ending anchor point Shapes are closed paths You can also draw closed
paths from scratch with thePen tool
To close a path Click the original anchor with
the Pen tool to complete anobject
To create closed paths fromselected objects, chooseObject > Path > Join

Extending a path with the Pen tool
ADD ANCHOR POINTS
Restraint! Fewer is better Fewer anchor points =
smaller file size Fewer anchor points =
smoother paths Fewer anchor points =
more easily editablepaths
When you need moreanchor points… Click with the Pen tool
on a path toautomatically add ananchor point
OR Click with the Add
Anchor Point tool in thePen tool group
Copyright © 2013 MyGraphicsLab / Pearson Education
Reducing the number of anchor points canradically simplify a traced image path.
DELETE ANCHOR POINTS
Deleting an anchor point deletes theline segment that it defined
Two ways to delete an anchor point Select the Delete Anchor Point tool
and click on the point Select the anchor with the Direct
Selection tool and press Delete onthe keyboard
Reduce the number of anchorpoints Select the anchor(s) with the Direct
Selection tool and choose Object >Path > Delete Anchor Points
To simplify a path and removepossibly unnecessary anchors,choose Object > Path > Simplify

Adjusting a curve with the Convert Anchor Point tool
CONVERT ANCHOR POINTS
The Convert Anchor Point tool: Converts straight angles to
curved anchors Converts curved anchors to
straight angles To convert an anchor point
Click a curved anchor point toconvert it to a straight angle
Click and drag a straight angleanchor point to convert it to acurve
Use the Convert Anchor Pointtool to click and drag anchorcontrol points to fine-tune acurve

Reshaping an object with the Direct Selection tool
MOVE ANCHOR POINTS
Click and drag on an anchor withthe Direct Selection tool to move itand reshape a drawing or shape
Copyright © 2013 MyGraphicsLab / Pearson Education
ALIGN ANCHOR POINTS
Anchor points can be aligned – horizontally or vertically – with the Align panel OR You can use Smart Guides to align anchors as you draw or edit a path
Copyright © 2013 MyGraphicsLab / Pearson Education
Moving two anchor points by moving a selected path segment
SELECTING PATH SEGMENTS
Path segments can beselected with the DirectSelection tool When you select a path,
you select the anchorpoints on either end ofthe path segment
When you move aselected path, you movethe anchor points at bothends of the path
When you delete aselected path in a closedpath, you convert it to anopen path

Smoothing a Pencil tool path with the Smooth tool
DRAW WITH THE PENCIL TOOL
Generates anchor points, but ismore intuitive than the Pen tool Pencil tool paths can easily be
extended with the Pencil tool Pencil tool paths can be edited
with the Pen tool – this isadjustable in the Pencil ToolOptions dialog box
Copyright © 2013 MyGraphicsLab / Pearson Education
Setting options for the Pencil tool to pick up and extend existing paths
SMOOTHING PENCIL TOOL DRAWING
Double-click the Penciltool to open the PencilTool Options dialog boxand adjust smoothness
Use the Smooth tool tosmooth Pencil tool paths

USING THE ERASER TOOL
The Eraser tool simulates the behavior of a regularpencil eraser
The Eraser tool works on selected objects If no objects are selected, the Eraser tool works on any
object to which it is applied The Eraser tool “cuts holes” in shapes Not all objects are “erasable” – the Eraser tool does
not work on raster images, type, and other objects

Using the Path Eraser tool to remove an area of the stroke
USING THE PATH ERASER TOOL
The Path Eraser Tool… Divides paths Can be found on the
Pencil tool tear-offmenu

Editing a path in Outline view
WORKING WITH PATHS IN OUTLINE VIEW
Outline view Displays only paths, not fills or effects Allows editing
Good for… Identifying and isolating paths Editing paths quickly, without waiting for effects to apply Choose View > Outline to toggle on or off
Copyright © 2013 MyGraphicsLab / Pearson Education
Left: The original stroke. Right: The outline.
OUTLINE PATHS TO CREATE SHAPES
Selected paths can beconverted to shapes,with the outline of thepath converted to astroke: Choose Object >Path > Outline Stroke
A handy technique forturning a thick strokeinto a path surroundingan editable fill
Tends to generate toomany anchor points –often takes a bit ofcleaning up

WHAT YOU CAN DO NOW
Edit paths generated by shapes with: The Direct Selection tool The pen tools The Pencil tool The Path Eraser tool
Draw paths with the Pen tool Draw paths with the Pencil tool Cut “holes” in fills with the Eraser tool

REVIEW: KEY POINTS
The Pen tool For drawing illustrations For generating scalable, easily editable vector files
Drawing with the Pencil tool Intuitive, like drawing with a real pencil Smoothness is adjustable in the tool dialog, or smoothable
with the Smooth tool
