ArcPropertyExtractor

Extracts the properties of arc geometry, storing the resulting values as attributes.

Jump to Configuration

Typical Uses

  • Making arc geometry properties accessible

  • Storing arc geometry properties for use elsewhere in a workspace

How does it work?

The ArcPropertyExtractor receives features with arc geometry and extracts their geometry properties into attributes.

Extracted properties include:

  • Primary Radius

  • Secondary Radius

  • Rotation

  • Start and Sweep Angle

  • Start X, Y and Z coordinates

  • End X, Y and Z coordinates

  • Center X, Y and Z coordinates

Values are calculated and extracted for all requested properties, regardless of the input arc geometry type.

To exclude an attribute, leave the parameter blank and it will not be added to the output features.

Feature geometry is unchanged.

Features without valid arc geometry are rejected, including ellipses.

For more information on arc geometry and types, see Arc.

Examples

Usage Notes

  • Paths with arc segments (such as the output of the Curvefitter) must be split into their components before using the ArcPropertyExtractor. See PathSplitter.

Creating and Modifying Arcs, Circles, and Ellipses

These transformers work with arcs in a variety of ways.

Output Ports

Note  Feature order may change in relation to other output ports. Feature order per port is maintained.

Parameters

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.

For more information, see Transformer Parameter Menu Options.
