Arc

class ansys.geometry.core.sketch.arc.Arc(start: ansys.geometry.core.math.point.Point2D, end: ansys.geometry.core.math.point.Point2D, center: ansys.geometry.core.math.point.Point2D, clockwise: bool = False)

Bases: ansys.geometry.core.sketch.edge.SketchEdge

Provides for modeling an arc.

Parameters:

startPoint2D

Starting point of the arc.

endPoint2D

Ending point of the arc.

centerPoint2D

Center point of the arc.

clockwisebool, default: False

Whether the arc spans the clockwise angle between the start and end points. When False (default), the arc spans the counter-clockwise angle. When True, the arc spands the clockwise angle.

property Arc.is_clockwise: bool

Flag indicating whether the rotation of the angle is clockwise.

Returns:

bool

True if the sense of rotation is clockwise. False if the sense of rotation is counter-clockwise.

property Arc.sector_area: pint.Quantity

Area of the sector of the arc.

property Arc.visualization_polydata: pyvista.PolyData

classmethod Arc.from_three_points(start: ansys.geometry.core.math.point.Point2D, inter: ansys.geometry.core.math.point.Point2D, end: ansys.geometry.core.math.point.Point2D)

Create an arc from three given points.

Parameters:

startPoint2D

Starting point of the arc.

interPoint2D

Intermediate point (location) of the arc.

endPoint2D

Ending point of the arc.

Returns:

Arc

Arc generated from the three points.

classmethod Arc.from_start_end_and_radius(start: ansys.geometry.core.math.point.Point2D, end: ansys.geometry.core.math.point.Point2D, radius: pint.Quantity | ansys.geometry.core.misc.measurements.Distance | ansys.geometry.core.typing.Real, convex_arc: bool = False, clockwise: bool = False)

Create an arc from a starting point, an ending point, and a radius.

Parameters:

startPoint2D

Starting point of the arc.

endPoint2D

Ending point of the arc.

radiusQuantity | Distance | Real

Radius of the arc.

convex_arcbool, default: False

Whether the arc is convex. The default is False. When False, the arc is concave. When True, the arc is convex.

clockwisebool, default: False

Whether the arc spans the clockwise angle between the start and end points. When False, the arc spans the counter-clockwise angle. When True, the arc spands the clockwise angle.

Returns:

Arc

Arc generated from the three points.

classmethod Arc.from_start_center_and_angle(start: ansys.geometry.core.math.point.Point2D, center: ansys.geometry.core.math.point.Point2D, angle: ansys.geometry.core.misc.measurements.Angle | pint.Quantity | ansys.geometry.core.typing.Real, clockwise: bool = False)

Create an arc from a starting point, a center point, and an angle.

Parameters:

startPoint2D

Starting point of the arc.

centerPoint2D

Center point of the arc.

angleAngle | Quantity | Real

Angle of the arc.

clockwisebool, default: False

Whether the provided angle should be considered clockwise. When False, the angle is considered counter-clockwise. When True, the angle is considered clockwise.

Returns:

Arc

Arc generated from the three points.
