The Oval Tool is used to create ovals or circles within a drawing. To use the tool, simply select it and then perform a Click/Drag combination at the point in the drawing panel where one of the bounding corners of the oval or circle should be. Drag in any direction and release the Click action where the other bounding corner should be.
Using the Oval Tool while holding down the Shift key allows for the creation of perfect circles by constraining the width and the height of the created object to equal values.
An oval can also contain text. See the Handling Text section for additional details.
Additional Oval Tool options are made available when an extended Click action is performed over the tool button.
This Circle Tool creates a perfect circle where the radius increases in increments as the size of the shape increases.
