Transforming a Range of Points

Use the magnet to transform a range of deform mesh surface points. In the Deform Mesh menu, the magnet controls include the Magnet button, the Magnet Transformation box, and the Magnet Curve Editor. The magnet controls work the same way as the magnet controls in the Extended Bicubic menu. See Transforming Multiple Points.
