#### 3.9.1.7. Elliptical Arc Element

 Description An element representing an 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) Center - [LENGTH] – Center point of the arc defined in the sketch's coordinate system. (IPoint/Location) Major Axis Point - [LENGTH] - Point of the major axis of the ellipse defined in the sketch's coordinate system. This point also defines the major radius. (IPoint/Location) Minor To Major Radius Ratio - Ratio of minor to major radii. (ICenterEllipticalArc/MinorToMajorRatio) Start Angle - [PHASE] - Start angle of the arc. Zero is defined to be at the major axis point. (ICenterEllipticalArc/StartAngle) End Angle - [PHASE] - End angle of the arc. (ICenterEllipticalArc/EndAngle) Counterclockwise - If True, the direction of the arc is counter clockwise. (ICenterEllipticalArc/Counterclockwise) Evaluated Locations/Center - [LENGTH] - Post-operation center location of the arc defined in the sketch's coordinate system. This is a calculated value based on the center, axes, start angle, end angle of the arc and any subsequent operations applied to the element. Read only. Evaluated Locations/Major Axis - [LENGTH] - Post-operation major axis of the arc defined in the sketch's coordinate system. This is a calculated value based on the center, axes, start angle, end angle of the arc and any subsequent operations applied to the element. Read only. Evaluated Locations/Start - [LENGTH] - Post-operation start location of the arc defined in the sketch's coordinate system. This is a calculated value based on the center, axes, start angle, end angle of the arc and any subsequent operations applied to the element. Read only. (ICenterEllipticalArc/Start) Evaluated Locations/End - [LENGTH] - Post-operation end location of the arc defined in the sketch's coordinate system. This is a calculated value based on the center, axes, start angle, end angle of the arc and any subsequent operations applied to the element. Read only. (ICenterEllipticalArc/End) Sketch Parameters: Label – A unique name that identifies the sketch. (ISketch/Label) Plane – Plane of the solid's coordinate system that the sketch lies in. (ISketch/Plane) Offset - [LENGTH] – Distance from the origin of the solid's coordinate system to the sketch plane in a direction normal to the chosen sketch plane.
