# Ellipse

fme_type = fme_ellipse

Ellipses, like arcs, are circular or elliptical. The boundary of an ellipse is specified by an arc, where the complete circuit along the arc is assumed. (For example, a sweep angle of 360 degrees.)

The boundary of an ellipse is an arc.

Ellipses may follow either the right- or left-hand rule (clockwise or counterclockwise in orientation).

## Ellipse Attributes

- fme_geometry = fme_point
- fme_type = fme_ellipse
- fme_rotation: The rotation of the primary axis in degrees counterclockwise from horizontal. If not set, then 0 is assumed.
- fme_primary_axis: The length of the primary semi-axis of the ellipse measured in ground units.
- fme_secondary_axis: The length of the secondary semi-axis of the ellipse measured in ground units. For circles this value will be equal to the fme_primary_axis. This attribute is optional. If not present, it is assumed to be a circular ellipse with the same value as fme_primary_axis.
