An ellipse is a useful object and one that is virtually impossible to create freehand. The Ellipse Tool takes the hassle out of creating circles and ellipses.
Settings
The following settings can be adjusted from the context toolbar:
Fill/Stroke—options to set the shape's fill and line color, as well as line weight.
Convert to Donut—Swaps the ellipse for a donut shape.
Convert to Pie—Swaps the ellipse for a pie shape.
Show Rotation Center—displays a movable rotation center about which the shape can be rotated.
Hide Selection—when selected, the object's selection box is temporarily hidden when transforming the object. If this option is off, the selection box remains visible during transformation. The selected behavior persists across all objects unless it is manually switched.
Reset Selection Box—after reshaping, rotating, or shearing the shape, this option resets the selection box to vertical.
Convert to Curves—converts the selected object into a series of connected lines and nodes.
