# How to interact with cubic bezier segments efficiently

3 Sep 20204 minutes to read

While interacting with multiple cubic bezier segments, you can maintain their control points in same distance and angle by using BezierSmoothness property of `CubicCurveSegment` class.

BezierSmoothness value Description Output
SymmetricDistance Both segments intersecting control points will be in same distance when any one them is editing
SymmetricAngle Both segments intersecting control points will be in same angle when any one them is editing
Symmetric Both segments intersecting control points will be in same angle and same distance when any one them is editing
None Segemnts control points are independent to each other
