Donut Tool

Customization

The Donut Tool has the option on the shape and on the context toolbar to control the size of the hole and completion of the circle.

The following settings can be adjusted from the context toolbar:

Hole Radius—controls the width of the hole at the shape's center.
Start/End Angle—sets the position of the start/end stops relative to 360°. The greater the difference in the angles, the larger the portion of pie.
Invert Angle—switches the Start and End angle values. This converts acute shapes to obtuse (and vice versa) and flips the shape horizontally and/or vertically.
Close Pie—if the circle is incomplete, closes the shape to create a full circle.
To Curves—converts the selected object into a series of connected lines and nodes.
