Friction allows user to hand draw a path with 2 modes :

• Automatic fitting : user can set Max Error (how far from the original curve the path is) and Smooth parameters, friction will try to adapt user's hand drawn curve accordingly
• Manual fitting : user draws a curve, then select some matching points on it to build the path with manual precision

Pick the one which better fits your need !

Do you know friction ? It is an awesome open source 2d animation software, early stage, which could replace after effect
