#### 3.9.1.11. Tangent at Start and End Elliptical Arc Element

 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] – Post-operation 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] – Post-operation 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] – Post-operation 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] – Post-operation 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. Example(s)  User Interface Button Command Details Mouse click order is: 1. Start point 2. Start tangent point 3. End tangent point 4. End point 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. Other Notes None.
