Description 
An element representing a segment of an ellipse, defined by four points. The first two points define a line that is tangential to the starting point of the elliptical arc, and the last two points define a line that is tangential to the ending point of the elliptical arc. 
Parameters 
Label – A unique name that identifies the element. (IElement/Label) Visible  If True, element is visible in the sketch. (IElement/Visible) Construction Only  If True, element is excluded from the covering process and does not become part of the geometry. Such elements are used in constructing other elements. (IElement/Construction) Start Tangent Point  [LENGTH] – The first point for the start tangent line. Defined in the sketch's coordinate system. (IPoint/Location) Start  [LENGTH] – The starting point for the elliptical arc, and the second point for the start tangent line. Defined in the sketch's coordinate system. (IPoint/Location) End  [LENGTH] – The end point for the elliptical arc, and the first point for the end tangent line. Defined in the sketch's coordinate system. (IPoint/Location) End Tangent Point  [LENGTH]  The second point for the end tangent line. Defined in the sketch's coordinate system. (IPoint/Location) Axes Orientation  Indicates the desired orientation of the ellipse major and minor axes. Axes Orientation/Start Tangent Line  Align the major axis of the ellipse parallel to the start tangent line. Axes Orientation/End Tangent Line  Align the major axis of the ellipse parallel to the end tangent line. Axes Orientation/Local Coordinate System Aligned  Align the major axis of the ellipse parallel to the coordinate axes. Evaluated Locations/Start Tangent Point  [LENGTH] – Postoperation start tangent point defined in the sketch's coordinate system. This is a calculated value based on the start tangent point of the ellipse and any subsequent operations applied to the element. Read only. Evaluated Locations/Start  [LENGTH] – Postoperation location of start point of the ellipse defined in the sketch's coordinate system. This is a calculated value based on the location of the start point and any subsequent operations applied to the element. Read only. Evaluated Locations/End  [LENGTH] – Postoperation location of end point of the ellipse defined in the sketch's coordinate system. This is a calculated value based on the location of the end point and any subsequent operations applied to the element. Read only. Evaluated Locations/End Tangent Point  [LENGTH] – Postoperation end tangent point of the ellipse segment, defined in the sketch's coordinate system. This is a calculated value based on the end tangent point of the ellipse and any subsequent operations applied to the element. Read only.

Requirements 
If a valid ellipse cannot be defined by the tangents, start and end points, and axes selection, the element is drawn as a straight line segment.
