To draw a curve:
1 Turn on the Curve window style control.
2 Click anywhere in the Viewer to start adding control points and drawing the shape
you need.
3 Click and drag to add and shape Bezier curves, or just click and release to add a
hard angle.
4 To finish drawing and close the shape, click the first control point you created to
create a corner, or click and drag on the first control point you created to create a
Bezier curve.
Once you’ve drawn a curve, there are many ways of manipulating it.
Simple methods of modifying a curve:
To add points: Click anywhere on a curve to add control points.
To reshape a curve: Drag any control point to a new location.
To move a curve: Drag anywhere within or just outside a curve to move it.
To symmetrically alter a Bezier curve: Drag any Bezier handle. The opposite handle
automatically moves in the other direction.
To asymmetrically alter a Bezier curve: Option-drag any Bezier handle. The opposite
handle stays in place while you drag the current handle. Once you’ve created an
asymmetric pair of Bezier handles, they move together as one if you simply drag a
handle. You need to Option-drag to change the angle.
To change a curve into a corner: Option-double-click any Bezier curve control point to
change it to a sharp-angled corner point.
To change a corner into a curve: Option-click any corner point and drag to pull out a
Bezier handle, changing it to a curve.
To remove points: Middle-click the control point you want to remove.
NOTE: Removing a control point from a Polygonal window that’s already been
animated using the Keyframe Editor results in that point abruptly popping on and off at
the keyframes creating the animation.
You can also Shift-drag a bounding box to select multiple control points on a curve to move,
delete, or transform them all at once.
You can Shift-drag a bounding box over multiple
control points to manipulate them all at once
