Blends Overview
You can use the Blend Tool to blend between two objects. The program creates a set of intermediate objects so you get a transition from the start object to the end object. you can change the number of steps in the blend and also have more than one stage so you can blend between several objects.
Simple Blends
These are quite simple blends - a simple transition from one object to another. Notice how you can blend from any type of object to any other type of object (the bottom example includes a letter X). To blend two objects, just choose the Blend Tool and drag from one object to another. For more details, see Blending objects.
Highlights
If you blend from one object to another which is on top of and smaller, you can easily create highlights. These are a sort of custom graduated fill.
Two-dimensional Blends
For effects such as this matrix, you can use a two-dimensional blend. For more details, see Creating two-way blends.
