#### Polar / Cartesian Toggle

This icon lets you switch your coordinate system between either Cartesian or Polar modes. These choices allow you to select the coordinate system that will be used to display the point or center values for the auto feature.

- In Cartesian mode, when the icon is depressed, the values are displayed in XYZ.

- In Polar mode, when the icon is raised, the values are displayed as radius, angle and height (shown as R, A, and H in the dialog box). The height depends on the workplane currently being used. If the current workplane is ZPLUS, the height is the Z value.
