Anchor points also appear in the mesh (differentiated by their square rather than diamond 
shape), and can be added, deleted, edited, and moved as with any anchor points in 
Illustrator. Anchor points can be placed on any mesh line; you can click an anchor point 
and drag its direction lines to modify it. (See 
.) 
The area between any four mesh points is called the mesh patch. You can also change the 
color of the mesh patch using the same techniques as changing colors on a mesh point.

Tips for creating mesh objects
You can create a mesh object out of any path object, or any bitmap image (such as a 
photographic image imported from Adobe Photoshop). There are a few important guide-
lines to keep in mind when creating mesh objects:
You cannot create mesh objects from compound paths, text objects, or linked EPS files.
Once a mesh object has been created, it cannot be converted back to a path object.
When converting complex objects, use the Create Mesh command for the best results. 
When converting simple objects, use either the mesh tool or the Create Mesh 
command. However, if you want to add a highlight to a particular spot, use the mesh 
tool and click at the point you want the highlight to appear.
To create a mesh object with a regular pattern of mesh points and mesh lines, use the 
Create Mesh command. 
When converting complex objects, Illustrator can add hidden anchor points to maintain 
the shape of a line. If you want to edit, add, or delete one or more of these anchor 
points, use the add-anchor-point tool or the delete-anchor-point tool.
To improve performance and speed of redrawing, keep the size of mesh objects to a 
minimum. Complex mesh objects can greatly reduce performance. Therefore, it is 
better to create a few small, simple mesh objects than to create a single, complex mesh 
object.
Creating a mesh object
Use the mesh tool or the Create Gradient Mesh command to convert objects to mesh 
objects. You can also use the Expand command to convert radial or linear gradient path 
objects into mesh objects.
To create a mesh object with the mesh tool:
Choose the mesh tool   and click a filled object. The object is converted to a mesh object 
with the minimum number of mesh lines.
