# 曲线部件¶

## 控制工具¶

Controls how the control points affect the curve shape. It determines the interpolation of the curve segment at the selected control point.

Free Handle

The handles can be moved completely independently, and thus can result in a sharp change of direction.

Aligned Free Handles

The two handles of the curve point are locked together to always point in exactly opposite directions. This results in a curve that is always smooth at the control point.
