CG INFINITY: CHAPTER TWO 295

Change the shape of the path by dragging the node or one of the
control handles. Dragging the node repositions it while dragging a
control handle changes the curvature of the path around the active
node and between the preceding and following nodes. You can control
the behavior of these nodes as well as their directions by choosing one
of the node options on the Attribute toolbar. In all, there are five
options you to choose from:
Curve Segment changes the curvature of a path between the preced-
ing, following and active nodes.
Linear Segment changes the shape of the path to straight line seg-
ments beginning from the preceding node to the active node.
Symmetric Node changes the curvature of the path between the
preceding, following and active nodes, keeping the control handles
fixed in a linear path and equal in length. (This button is active only if
the Curved Node option is selected). This option is best for performing
general changes to a path’s curvature.
Smooth Node changes the curvature of the path between the preced-
ing, following and active nodes, allowing you to change the length of
the control handles independently from each other (they still remain on
a linear path). Use this option for greater control over the curvature
with respect to the preceding and following nodes.
Cusp Node changes the curvature of the path between the preceding,
following and active nodes, allowing you to move one control handle at
a time. This is useful when you want to change the curve on one side
of the path without affecting the other.

Keep dragging nodes and control handles until you have a shape you
are happy with.
Notes:
• To add a node, click anywhere along the path of the object with the Add Node
button selected from the Attribute toolbar. To remove a node, click the node
with the Remove Node button selected.
• You can make a path closed or opened by clicking the respective buttons on
the Attribute toolbar.
