2DEllipseReplacer

Replaces or creates feature geometry with a 2D ellipse as defined in parameters for center point, radii, and rotation.  

Jump to Configuration

Typical Uses

  • Creating ellipse or circle geometry from attribute values or user parameters

  • Replacing point geometry with ellipses or circles defined by values

How does it work?

The 2DEllipseReplacer receives features of any kind and replaces their geometry with ellipses as defined in parameters.

The parameters describe an ellipse as a closed Arc By Center Point by the following:

  • Center X and Y coordinates

  • Primary and Secondary Axis (radii) in ground units

  • Rotation in degrees

  • An assumed sweep of 360 degrees

Values may be entered or provided through attribute values, expressions, or user parameters.

If the feature has point or ellipse geometry, and Center X and Y are left blank, the coordinates of the feature’s existing geometry will be used. If the feature has no geometry or geometry other than point or ellipse, the feature is rejected.

For more information on ellipse geometry see Ellipse.

Examples

Usage Notes

  • To create circles around point features, consider using a Bufferer.

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.
