Expanding 3D objects

A live 3D object in Illustrator is a simple cross section under the hood.

While this allows you to edit the basic cross section shape (and thus the

shape of the 3D object), you cannot select individual, shaded areas for

editing, because they are not literal, individually editable vectors. To

convert the live effects to editable vectors, expand the object (Object >

Expand Appearance). The result can be a collection of very complex

objects, but you gain some editability for individual components, and

often a reduction in file size. If you must expand a 3D object, it is

recommended that you work on a copy of the file, and keep an

unedited original as insurance.

Expanding Live Eects

A live 3D object (le) is a simple cross section under the hood (center). While this allows you

to edit the basic cross section shape (and thus the revolved object), you cannot select

individual, shaded areas for editing, because they are not “real.” To convert the live eects to

editable vectors (right) expand the object (Object > Expand Appearance).

Ensuring correct imaging of raster-based effects

Illustrator CS5 offers stylized soft-edge effects such as Drop Shadow,

Feather, and Inner Glow, which are rendered as pixels during output.

While these effects are live and editable, their resolution during output

is governed by the Document Raster Effects setting (Effects > Document

Raster Effects Settings). By default, the Raster Effects setting in

Illustrator CS5 is 300 ppi when using the Print document profile, which

should be sufficient for most printing needs. However, files created in

earlier versions of Illustrator (of with the Web or RGB document profile)

may be set up with the previous default setting for Raster Effects of 72

ppi. The low resolution may not be obvious on screen, but it will be

apparent in output. Because these effects are live effects, rather than

literal image content, changing the Raster Effects resolution will correct

the resolution of the effects: Choose Effect > Document Raster Effects

Settings to specify an appropriate resolution for your output

requirements.

If you need to modify effects in an Illustrator file supplied by a

customer, open the Appearance panel (Window > Appearance), click

the effect entry in the panel and modify the settings as necessary.

Editing warps and envelope distortions

Illustrator CS5 offers methods for distorting text and other objects,

using a feature called Envelope Distort. Select an object or text with the

Selection tool, choose Object > Envelope Distort, and select from the

available options:

•Make with Warp: Lets you choose from the 15 default Warp shapes,

including Arc, Bulge, Flag, Fisheye, and others. Each Warp option

oers controls over vertical and horizontal distortions.

•Make with Mesh: Sets the number of rows and columns, and Illustra-

tor creates an editable mesh. Select the anchors and control handles

to manipulation the distortion manually.

•Make with Top Object: Lets you create any shape with the geometric

tools (ellipses, stars, and so on) or draw a shape (open or closed) with

the Pen tool. Place the shape above the text or other object you wish

to distort (higher in stacking order). Select the top object and the

object you wish to distort, and Illustrator will distort the object using

the top object as a guide.
