Smart Curve

Create curves and define advanced parameters. This tool allows us to create complex curves very quickly.

Steps:

1. Select the points with which we want to define the curve.

2. We can change such parameters as "closed" or "symmetry" at any moment. We can define four "symmetry" options: None, Vertical, Horizontal or Quadruple.

3. There is a function that allows us to add a vertex to the curve. By clicking on any point and pressing on the Ctrl key we are able to add a vertex. The Undo option allows us to delete the last selected point.
