Sets the properties of an arc geometry to those specified. All parameters are optional; if a value is unspecified, it is left unmodified on the geometry. This transformer works on a single feature at a time.
This transformer can also be used to create an arc by using a point as an input. The point geometry will be used as the center point for the new arc. When using this creation mode, you must supply, at minimum, the following parameters: Primary Radius, Start Angle, Sweep Angle.
Input Ports
Input
Features with arc or point geometry.
Output Ports
Output
Features with the properties of the arc geometry modified according to the new values provided, or the newly created arc geometry.
<Rejected>
Invalid features will be output via this port.
Parameters
Primary Radius
The new length of the primary radius for the ellipse upon which the arc is based.
Secondary Radius
The new length of the secondary radius for the ellipse upon which the arc is based.
Rotation
The new rotation of the ellipse that defines the arc. The rotation angle specifies the angle in degrees from the horizontal axis to the primary axis in a counterclockwise direction.
Start Angle
The new parametric angle of the start point of the arc, in degrees.
Sweep Angle
The new parametric sweep angle of the start arc, in degrees.
The default is 360.
Start X
The new x coordinate value for the arc’s start point
Start Y
The new y coordinate value for the arc’s start point
Start Z
The new z coordinate value for the arc’s start point
End X
The new x coordinate value for the arc’s end point
End Y
The new y coordinate value for the arc’s end point
End Z
The new z coordinate value for the arc’s end point
Center X
The new x coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.
Center Y
The new y coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.
Center Z
The new z coordinate of the center of the ellipse. If not specified, the first coordinate of the feature is used.

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.
