Arc2D Object

Derived from: Curve2D Object
Defined in namespace "adsk::core" and the header file is <Core/Geometry/Arc2D.h>

Description

Transient 2D arc. A transient arc is not displayed or saved in a document. Transient arcs are used as a wrapper to work with raw 2D arc information. They are created statically using one of the create methods supported by the Arc2D class.

Methods

Name Description
classType Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().
copy Creates and returns an independent copy of this Arc2D object.
createByCenter Creates a transient 2D arc object specifying the center, radius and start and end angles. A transient arc is not displayed or saved in a document. Transient arcs are used as a wrapper to work with raw 2D arc information.
createByThreePoints Creates a transient 2D arc by specifying 3 points. A transient arc is not displayed or saved in a document. Transient arcs are used as a wrapper to work with raw 2D arc information.
getData Gets all of the data defining the arc.
set Sets all of the data defining the arc.
transformBy Transforms this curve in 2D space.

Properties

Name Description
asNurbsCurve Returns a NURBS curve that is geometrically identical to the arc.
center Gets and sets the center position of the arc.
curveType Returns the type of geometry this curve represents.
endAngle Gets and sets the end angle of the arc in radians, where 0 is along the x axis.
endPoint Gets the position of the end point of the arc.
evaluator Returns an evaluator object that lets you perform additional evaluations on the curve.
isClockwise Gets if the sweep direction of the arc is clockwise or counterclockwise.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
objectType This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object.

It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():
radius Gets and sets the radius of the arc.
startAngle Gets and sets the start angle of the arc in radians, where 0 is along the x axis.
startPoint Gets the position of the start point of the arc.
