2DEllipseReplacer
Replaces the geometry of the feature with a two-dimensional ellipse whose shape is set by the parameters, values or the values of existing attributes.
Input Ports
This transformer accepts any feature.
Output Ports
If only one of Center X and Center Y is specified, then all features are output through the <Rejected> port. If neither Center X nor Center Y is specified, features with non-ellipse/point geometries are output through the <Rejected> port.
Parameters
You can enter the parameters below as a number, or choose them from the value of a feature attribute by selecting the attribute name from the pull-down list.
The center x and y parameters set the origin of the ellipse. If these values are blank, and the input features are points or ellipses, the existing feature x/y values will determine the center of the ellipses. If the parameter values are blank, and the input features are not points/ellipses, they are output through the <Rejected> port.

The primary and secondary axis set the radii of the ellipse. Note that the primary axis need not be larger than the secondary, however, the rotation angle is always measured from the x axis to the primary axis. To make a circular arc, set both the primary and secondary axis to the same value.

The rotation angle is measured in degrees counterclockwise from horizontal, and measures the rotation of the primary axis from horizontal.
Usage Notes
If the parameters for the ellipse are not known and need to be calculated from a linear feature's geometry, you should use the ArcEstimator.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
