You can now create perfectly antialiased shapes, deform text to create incredible logos, and reshape and resize your work with no loss of definition. But to get the most out of this capability, you need to know about node editing. A little dry, but pretty much to the point.
Nodes are control points situated at the edges of vector objects.
In Node Editing mode they appear as small blue boxes connected by blue lines. Usually you'll find them situated at corners or places where curves change direction. You can move them around to change the shape of an object, or change their Node Type to effect how the lines before and after them behave. To edit vector shapes , you must go into node editing mode. This is done by selecting a particular shape with the vector selection tool and then clicking on the large Node Edit button that appears on the Tool Options palette To begin, every vector object has certain features, whether it's a simple line or a closed shape of some kind.
