perspective grid
- Slide 3
- Extrude Objects Extrude & Bevel effects apply three-
dimensional 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
- Slide 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.
- Slide 5
- Extrude Objects Objects before and after being extruded
- Slide 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.
- Slide 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.

- Slide 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.
- Slide 11
- Extrude Objects Choose from 10 bevel shapes

Bevel shapes applied to edges
- Slide 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.
- Slide 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.

- 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
- Slide 18
- Revolve Objects Revolving an object around its left edge
Revolving an object around its right edge
- Slide 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
- Slide 20
- Revolve Objects Options for revolving objects
- Slide 21
- Revolve Objects Identifying the path used to produce the
revolved 3D graphic
- Slide 22
- Revolve Objects A revolved graphic rotated four ways
- Slide 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.
- Slide 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.
- Slide 25
- Revolve Objects Two grouped paths revolved around a single
y-axis. Object before it is revolved. Object after it is
revolved.
- Slide 26
- Revolve Objects Four grouped paths after being revolved and
rotated
- Slide 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. Enter offset value here
- Slide 28
- Revolve Objects Object revolved with a 90- point offset from
its Y-axis Rotated object shows 90-point offset more clearly
- Slide 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.
- Slide 30
- When you revolve an object, four surface shadings are
available: Wireframe No Shading Diffuse Shading Plastic Shading
Manipulate Surface Shading and Lighting
- Slide 31
- Wireframe No Shading Diffuse Shading Plastic Shading Manipulate
Surface Shading and Lighting
- Slide 32
- 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. Manipulate Surface
Shading and Lighting
- Slide 33
- 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. Manipulate Surface Shading and Lighting
- Slide 34
- 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. Manipulate Surface Shading and Lighting

- Slide 38
- Map Artwork to 3D Objects You can map a 2-dimensional object to
a 3- dimensional object. For example, a label is a 2- dimensional
object that can be wrapped around a 3- dimensional can.
- Slide 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.
- Slide 40
- Map Artwork to 3D Objects Objects to be used for mapping
- Slide 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.
- Slide 42
- Map Artwork to 3D Objects Surface buttons Interior of curved
lines represents visible surface (1 of 4)
- Slide 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.
- Slide 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
- Slide 45
- Map Artwork to 3D Objects Wrapping Paper symbol selected
- Slide 46
- Map Artwork to 3D objects Symbol artwork is mapped to 3-D
object.
- Slide 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
- Slide 48
- Work with a Perspective Grid 1-point perspective grid 2-point
perspective grid3-point perspective grid
- Slide 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.
- Slide 50
- 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. Work with a Perspective
Grid
- Slide 51
- Save your grid settings as a named preset
- Slide 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.
- Slide 53
- Work with a Perspective Grid Left perspective plane is selected
Rectangle is drawn on left plane
- Slide 54
- Work with a Perspective Grid Once youve drawn objects in
perspective, use the Perspective Selection tool to click and drag
objects to move and modify them in perspective.
- Slide 55
- Work with a Perspective Grid Three copies of an ellipse dragged
and dropped with the Perspective Selection tool.
