3. Extrude Objects
• Extrude & Bevel effects apply threedimensional effects to two-dimensional
objects.
– Two-dimensional objects have two axes: X for
width and Y for height
– Three-dimensional objects have Z axis added
4. Extrude Objects
• Determine the degree of extrusion by
changing the Extrude Depth value in 3D
Extrude & Bevel Options dialog box.
• Use the Caps buttons in 3D Extrude & Bevel
Options dialog box to make objects appear
solid or hollow.
6. Extrude Objects
Rotating 3D objects
• The 3D Extrude & Bevel Options dialog box
offers controls for rotating extruded objects.
• Rotate manually by dragging rotation cube.
7. Extrude Objects
• When you rotate the cube, values on the X, Y, and
Z axes update to reflect the changes made.
• Enter values in these boxes to rotate object at
specific angles.
• Once you extrude an object, you can view any
surface – front, back, left, or right.
10. Extrude Objects
• The Bevel menu offers ten predefined bevel
shapes you can apply to the edge of an
extruded object.
• You control the width of a bevel edge with the
Height slider.
13. Extrude Objects
When Illustrator has difficulty rendering an
object with a beveled edge, a warning appears
in the 3D Extrude & Bevel Options dialog box.
14. Extrude Objects
• Sometimes there is no solution, but your best
bet is to reduce the bevel width.
• Decide how to apply bevel using the Bevel
Extent In and Bevel Extent Out buttons in 3D
Extrude & Bevel Options dialog box.

17. Revolve Objects
Revolving an object “sweeps” a path in a circular
direction around the Y axis.
– Surface shading is applied automatically
– By default, object revolved around the vertical axis
that represents leftmost point
– The 3D Revolve Options dialog box offers an
option to revolve object from right edge
19. Revolve Objects
• A revolution occurs around the vertical axis.
– Starting path will depict half of the object you want
to revolve
• Once revolved, an object can be rotated by
using the 3D Revolve Options dialog box.
– It presents all surfaces of the graphic
23. Revolve Objects
• Apply the Revolve effect to multiple paths
simultaneously.
– Can be open or closed paths
• When Revolve effect is applied to multiple
paths, each path is revolved around its own
axis.
24. Revolve Objects
Revolving grouped objects
• When grouped, multiple paths are revolved
around a single axis.
• When multiple paths are grouped and
revolved, they will also rotate together.
27. Revolve Objects
Increasing the
Offset value in
the 3D Revolve
Options dialog
box increases
how far from the
Y axis the object
is revolved.

29. Manipulate Surface Shading and Lighting
When you apply the Extrude & Bevel effect or
Revolve effect, surface shading and lighting is
applied automatically but can be manipulated.
30. Manipulate Surface Shading and Lighting
• When you revolve an object, four surface
shadings are available:
– Wireframe
– No Shading
– Diffuse Shading
– Plastic Shading
32. Manipulate Surface Shading and Lighting
When you choose Diffuse Shading or Plastic Shading, a
number of lighting controls are available.
•
•
•
•
•
Lighting Intensity controls strength of light on object.
Ambient Light determines how object is lit globally.
Highlight Intensity controls how intense highlight appears.
Highlight Size controls how large highlights appear.
Blend Steps controls how smoothly shading appears.
33. Manipulate Surface Shading and Lighting
When Diffuse Shading or Plastic Shading is
chosen, you can drag light source to a new
location to light an object from a different angle.
34. Manipulate Surface Shading and Lighting
• Add additional light sources by clicking New Light
button.
• Apply different light intensity values to individual light
sources.
• Delete a light source by selecting it, then clicking Delete
Light button.
• Move selected light to back button moves light source to
back.
38. Map Artwork to 3D Objects
You can map a
2-dimensional object to a 3dimensional object.
For example, a label is a 2dimensional object that can
be wrapped around a 3dimensional can.
39. Map Artwork to 3D Objects
• First convert 2D object to symbol.
• Select a 3D object.
• Click Map Art in the 3D Revolve Options
dialog box.
40. Map Artwork to 3D Objects
Objects to be used for mapping
41. Map Artwork to 3D Objects
• In the Map Art dialog box choose which
surface you want to map the art on.
• When you click a surface button, active
surface is shown in red wireframe on 3D
object.
42. Map Artwork to 3D Objects
Surface buttons
Interior of curved lines represents visible surface (1 of 4)
43. Map Artwork to 3D Objects
• Grid pattern represents the complete surface
of the object.
• Includes the entire surface around the object
that you may not see.
44. Map Artwork to 3D Objects
• Once surface chosen, choose symbol to be
mapped by clicking the Symbol list arrow.
– Symbol artwork is centered on grid.
– Drag artwork so it completely covers curved lines
– Once artwork is mapped, it reshapes itself to the
three-dimensional object

47. Work with a Perspective Grid
• Use the Perspective Grid feature to draw and
create objects in perspective.
• Three types of grids:
– 1-point perspective
– 2-point perspective
– 3-point perspective
48. Work with a Perspective Grid
1-point perspective grid
2-point perspective grid
3-point perspective grid
49. Work with a Perspective Grid
• Point refers to vanishing point.
• 2-point perspective is the default.
• Click the Perspective Grid tool on the Tools
panel to access the grid.
• Or select to show it on the View menu.
• You can resize and reshape the grid.
50. Work with a Perspective Grid
• Save your modified grid as a Perspective Grid
Preset.
• You can modify your saved preset.
• When you are in Perspective Grid mode, the
basic shape tools draw in perspective.
51. Work with a Perspective Grid
Save your
grid
settings

52. Work with a Perspective Grid
• Specify on which
perspective plane you
want to draw by clicking
one of the faces on the
Plane Switching Widget.
53. Work with a Perspective Grid
Left perspective
plane is selected
Rectangle is drawn
on left plane
54. Work with a Perspective Grid
Once you’ve drawn objects in perspective, use
the Perspective Selection tool to click and drag
objects to move and modify them in
perspective.
