Arc2D Object
Derived from: Curve2D ObjectDefined 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. |
