Donut Spline 271
Closedpieslicearcs
Reverse—When on, the direction of the arc spline
is reversed, and the first vertex is placed at the
opposite end of an open arc. As long as the shape
remains an original shape (and not an editable
spline), you c an switch its direction by toggling
Reverse. Once the arc is converted to an editable
spline, you can use Reverse at the Spline sub-object
level to reverse direction.

Use D onut to create closed shapes from two
concentric circles. Each circle is made of four
vertices.

Procedure
To create a donut:
1.
GototheCreatepanelandchoose
Shapes.
2. Click Donut.
3. Chooseacreationmethod.
4. Drag and release the mouse button to define
the first donut circle.
5. Move the mouse and then click to define the
radius of the second concentric donut circle.

Rendering and Interpolation rollouts
All spline-based shapes share these parameters.
See
Splines (page 1–261) for explanations of these
parameters.
Creation Meth od rollout
The Donut shape uses the standard creation
methodsofCenterorEdge. Mostspline-based
shapes share the same Creation Metho d
parameters. See
Splines (page 1–261) for an
explanation of these parameters.
Parameters rollout
Once you have created a donut, you can make
changes using the following parameters:
Radius 1—Sets the radius of the first c ircle.
Radius 2—Sets the radius of the second circle.
