After expanding the gradients into gradient mesh objects
3 Editing meshes. You can use several tools to edit gradient mesh objects (use isolation
mode, or lock/hide objects on specific layers as you work). The Mesh tool combines
the functionality of the Direct Selection tool with the ability to add mesh lines. With
the Mesh tool, click exactly on a mesh anchor point to select or move that point or its
direction handles. Or, click anywhere within a mesh, except on an anchor point, to
add a new mesh point and gridline. You can also use the Add Anchor Point tool (click
and hold to choose it from the Pen tool pop-up) to add a point without a gridline. To
delete a selected anchor point, press the Delete key; if that point is a mesh point, the
gridlines will be deleted as well.
