Sets the properties of an ellipse geometry.
This transformer can also be used to create an ellipse by using a point as an input. The point geometry will be used as the center point for the new ellipse. When using this creation mode, you must supply, at minimum, the following parameter: New Primary Radius.
Features with ellipse geometry or point geometry.
Features with the properties of the ellipse geometry modified according to the new values provided, or the newly created ellipse geometry.
Invalid features will be output via this port.
Each parameter may either be entered as a number, or taken from the value of a feature attribute by selecting the attribute name from the pull-down list. All parameters are optional. If a value is unspecified, it will be left unmodified on the geometry.
The primary and secondary radius set the radii of the arc. Note that the primary radius need not be larger than the secondary, however, the rotation angle is always measured from the x axis to the primary axis. To make a circular arc, set both the primary and secondary radius to the same value.
The rotation angle is measured in degrees counterclockwise from horizontal, and measures the rotation of the primary axis from horizontal.
This parameter can adjust the orientation of a feature to follow the right-hand rule or the left-hand rule1http://en.wikipedia.org/wiki/Right-hand_rule.
The center x, y and z parameters set the origin of the arc. If these values are blank, and the input features are points, the existing feature x/y/z values will determine the center of the arcs. If the parameter values are blank, and the input features are not points, the operation is undefined.
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.
