Drawing

• Select the anchor point where you want to split the path, and then click the Cut Path At Selected Anchor Points

button

in the Control panel. When you split the path at an anchor point, a new anchor point appears on top

of the original anchor point, and one anchor point is selected.

3 Use the Direct Selection tool to adjust the new anchor point or path segment.

Note: You can divide an object into separate component faces by using the Knife tool (a face is an area undivided by a

line segment).

Tracing artwork with Live Trace

Trace artwork

If you want to base a new drawing on an existing piece of artwork, you can trace it. For example, you can create a

graphic based on a pencil sketch drawn on paper or on a raster image saved in another graphics program by bringing

the graphic into Illustrator and tracing over it.

The easiest way to trace artwork is to open or place a file into Illustrator and automatically trace the artwork with the

Live Trace command. You can control the level of detail and how the tracing is filled. When you are satisfied with the

tracing results, you can convert the tracing to vector paths or a Live Paint object.

Before and after tracing a bitmap image with the Live Trace command

For a video on using Live Trace, see www.adobe.com/go/vid0043. For examples on using a template layer for tracing,

see the following tutorials: www.adobe.com/go/learn_ai_tutorials_templatelayer_en and

www.adobe.com/go/learn_ai_tutorials_elliptical_gradients_en.

Automatically trace artwork using Live Trace

1 Open or place a file to use as the source image for the tracing.

2 With the source image selected, do one of the following:

• To trace the image using a tracing preset, click the Tracing Presets and Options button in the Control panel,

and select a preset.

• To trace the image using the default tracing options, click Live Trace in the Control panel, or choose Object >

Live Trace

> Make.

• To set tracing options before you trace the image, click the Tracing Presets and Options button in the

Control panel, and choose Tracing Options. Alternatively, choose Object > Live Trace > Tracing Options. Set

tracing options, and then click Trace.

3 (Optional) Adjust the results of the tracing.
