3.7.1.7. 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. (ISketch/PlaneOffset)

Example(s)
