Sets the given attributes to the properties of an ellipse geometry.
Output Ports
Note: ">Note:Feature ordermay change in relation to other output ports. Feature order per port is maintained.
Parameters
Primary Radius Attribute
Attribute name that is set to the length of the primary radius for the ellipse upon which the arc is based.
Secondary Radius Attribute
属性名称设置为弧形为基于椭圆的次要半径的长度。
旋转属性
属性名称设置为定义弧的椭圆旋转。旋转角度以逆时针方向从水平轴线到初级轴的角度。
Orientation Attribute
Attribute name that is set to the orientation of the ellipse that defines the arc. The orientation of a feature will follow the right-hand rule or the left-hand rule1.
Center X Attribute
Attribute name that is set to the X coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.
Center Y Attribute
Attribute name that is set to the Y coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.
Center Z Attribute
Attribute name that is set to the Z coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.
Editing Transformer Parameters
使用一组菜单选项，可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能，例如高级编辑器和算术编辑器。要访问这些选项的菜单，请单击
beside the applicable parameter. For more information, see变压器参数菜单选项.
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.
How to Set Parameter Values
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
设置值 - 无论是否直接在参数中输入或使用其中一个编辑器和包含字符串的表达式都是构造的，都会评估这些函数的字符串和表达式。因此，这些函数的名称（以@ <function_name.>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables

Table Tools
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
筛选
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
进口
|
进口populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note:Not all tools are available in all transformers.
