ArcStroker

Replaces arc or ellipse geometry with interpolated straight line segments.

Jump to Configuration

Typical Uses

  • Preparing geometry for transformation, reprojection, or formats where arcs are not supported

How does it work?

The ArcStroker receives features with vector geometry and converts any arcs to a series of interpolated line segments.

Ellipses are converted to polygons. Paths will have any arc segments stroked while passing through line segments unchanged.

The number of interpolated edges may be determined by:

  • Letting the ArcStroker choose a reasonable number (default)

  • Specifying an exact number of segments to create per arc (Stroke By > Number of Interpolated Edges)

  • Specifying the maximum distance the new line segments may be from the original arc position (Stroke By > Maximum Deviation)

This example shows a circular arc stroked with four (4) interpolated edges:

Examples

Usage Notes

  • Maximum deviation is a measurement in ground units. Features with a geographic (lat/long) coordinate system may need to be reprojected before using this option.

  • To reverse arc stroking, consider using the Curvefitter or ArcEstimator.

Creating and Modifying Arcs, Circles, and Ellipses

These transformers work with arcs in a variety of ways.

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.
