Manipulating Vertices and Tangents

You can manipulate vertices and tangents during and after mask creation. Edit vertices and tangents gesturally when the edit mode is set to Move or Break. Alternatively, edit them using the Vertices tab.

Vertices selected as a group can be transformed around a localized pivot. The angle and length of tangent handles can also be manipulated as a group.
