CircularArc2d(Point2d, Point2d, Double, Boolean) Constructor

Constructor for the CircularArc2d class. Creates an arc according to the specified parameters.

Namespace: Teigha.Geometry
Assembly: TD_Mgd (in TD_Mgd.dll) Version: 24.2.0.0

Syntax

public CircularArc2d(
        Point2d startPoint,
        Point2d endPoint,
        double bulge,
        bool bulgeFlag
)

Public Sub New ( 
        startPoint As Point2d,
        endPoint As Point2d,
        bulge As Double,
        bulgeFlag As Boolean
)

public:
CircularArc2d(
        Point2d startPoint, 
        Point2d endPoint, 
        double bulge, 
        bool bulgeFlag
)

new : 
        startPoint : Point2d * 
        endPoint : Point2d * 
        bulge : float * 
        bulgeFlag : bool -> CircularArc2d

Parameters

startPoint Point2d: [in] Start point of an arc.
endPoint Point2d: [in] End point of an arc.
bulge Double: [in] Bulge distance.
bulgeFlag Boolean: [in] Specifies how to calculate arc parameters according to the bulge distance.

Remarks

If a line between the startPoint and endPoint is drawn, the distance between this line and the midpoint of the arc is equal to the length of the bulge. If bulgeFlag is true, the bulge is interpreted as the maximum distance between the two input points between the arc and the chord. If bulgeFlag is false, the bulge is interpreted as the tangent of 1/4 of the included angle (tan(ang/4)), where ang is the angle of the arc segment between the two input points. The arc is constructed in counterclockwise direction. This constructor always creates an arc and cannot be used to construct a circle.
