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

Jump to Configuration

Typical Uses

  • Making ellipse geometry properties accessible

  • Storing ellipse geometry properties for use elsewhere in a workspace

How does it work?

The EllipsePropertyExtractor receives features with ellipse geometry and extracts their geometry properties into attributes.

Extracted properties include:

  • Primary Radius

  • Secondary Radius

  • Rotation

  • Orientation

  • Center X

  • Center Y

  • Center Z

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 ellipse geometry are rejected.

For more information on ellipse geometry see Ellipse.


Usage Notes

Creating and Modifying Arcs, Circles, and Ellipses

These transformers work with arcs in a variety of ways.


Input Ports

Output Ports

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


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.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
