There are two ways to transform points with the magnet. You can use the magnet to select a range of points
and transform them gesturally. Or, you can use the invisible magnet in conjunction with the Translation,
Rotation, and Scale fields to transform selected points numerically.
Before you can use the magnet, you must set the polarity of the magnet and the magnet area of focus. The
magnet's area of focus is determined by where you click the surface and the polarity of the magnet is set by
the Magnet Curve Editor. The radius is determined by the distance from the centre to the farthest selected
point.
Using the Magnet
Setting the Magnet Polarity
Use the Magnet Curve Editor to define the weighted polarity from the centre to the edge of the magnet.
Points are either attracted or repelled depending on their location in the magnet and the shape of the magnet
curve.
The area of the magnet is plotted on the X-axis where 0 is the centre of the magnet and 100 is the edge of
the magnet. The polarity is plotted on the Y-axis where 1 is maximum positive strength and -1 is maximum
negative strength.
A positive polarity value attracts nearby points. A negative polarity value repels nearby points. The following
example illustrates a magnet that has a strong positive polarity near the centre and strong negative polarity
near the edges.
