|
On a curved segment a selected anchor point displays one or two direction lines ending in direction points. The position, direction and length of the directionlines control the shape of a curve. Moving direction lines reshapes a curve. |
|||
| Direction lines are always tangent to the curve at the anchor points. The slope of each curve and the length of each direction point control the tangent direction and length of the curve. | |||
