1.Do one of the following with the Shape tool
Click and drag a segment. You can only move a segment in this manner if it is
a curved segment. Straight segments will not move.
Click and drag a node. As you drag, the segments on either side of the node
move. If the node is on a curved segment, the control points also move so that
the angles at which the curve enters and leaves the node remain unchanged.
Click a node. Control points only extend from the selected node and from
those nodes on either side of the selected node if it is on a curved segment. Click
and drag the control points.
Notes
Before you can shape a curve object, you must select it with the Shape tool.
You can change the shape of a curve object by moving its segments, nodes, and
control points. Normally, you move the segments and nodes to make coarse
adjustments, and then fine-tune the shape by moving the control points of the nodes.
Tip
To move a control point hidden under a node, deselect all nodes on the curve
object, hold down SHIFT, and click and drag the control point out from under
the node.
