The 2D ellipse is used for annotating round and elliptical objects in camera images, for example wheels or road markings. It is available when your task includes an ellipse class — select it in the [Create tab](docId\:i0ZNcPAdQC20kUIw8ZXZp) and draw with the **Ellipse** tool.

## Drawing tool

An ellipse is placed with three clicks:

::::WorkflowBlock
:::WorkflowBlockItem
Click the bottom center point.
:::

:::WorkflowBlockItem
Click the top center point.

The first two clicks define the height and the tilt of the ellipse.
:::

:::WorkflowBlockItem
Click either the left-most or right-most point on the line.

This sets the width, and the ellipse is created.
