To create a mesh object with the Create Mesh command:
Select a filled object.
Choose Object > Create Gradient Mesh.
Enter the number of horizontal rows of mesh lines to create on the object in the Rows 
text box.
Enter the number of vertical columns of mesh lines to create on the object in the 
Columns text box.
Select the direction of the highlight from the Appearance pop-up menu:
To Center creates a highlight in the center of the object. 
To Edge creates a highlight on the edges of the object.
Flat applies the object’s original color evenly across the surface, resulting in no 
highlight.
Enter a percentage of white highlight to apply to the mesh object. A value of 100% 
applies maximum white highlight to the object; a value of 0% applies no white highlight 
to the object.
Creating a mesh object using the Expand command:
Select an object containing a radial or linear gradient fill.
Choose Object > Expand.
Select the Gradient Mesh option in the Expand dialog box and click OK. The selected 
object is converted to a mesh object that takes the shape of the gradient, either circular 
(radial) or rectangular (linear). 
Editing mesh objects
Once you have created a mesh object, you can adjust or edit its mesh points, anchor 
points, and mesh lines. Anchor points can be added with the add-anchor-point tool or 
deleted with the delete-anchor-point tool on any mesh line. 
To add or delete mesh points and mesh lines:
Select the mesh tool  .
Do one of the following:
To add a mesh point colored with the current fill color, click anywhere in the mesh 
object. The corresponding mesh lines extend from the new mesh point to the edges of 
the object. Clicking on an existing mesh line adds a single intersecting mesh line.
To add a mesh point without changing to the current fill color, press Shift and click.
To delete a mesh point and the corresponding mesh lines, Alt-click (Windows) or 
Option-click (Mac OS) directly on the mesh point. 
To edit a mesh point:
Select the mesh tool and click directly on a mesh point. Direction lines appear on the 
mesh point.
