Manipulating segments
You can move curved segments to change an object’s shape. You can also control the smoothness of curved segments.
You can change the direction of a curve object by reversing the position of its start and end nodes. The effect is apparent only when the ends of a curve object are different. For example, when an arrowhead is applied to the end node of a curve object, changing the direction results in moving the arrowhead to the start node.
