Spring tutorial


Spring curves will interpolate what is in the middle of the fixed and rotating part of the curve.
This will distort the original curve but it will keep constant the two ends. This workflow has been
developed so that it mimic the one that is performed with paper pattern.

A new layer will be created and the new curves will be added to that layer.
