OdGeEllipArc2d Class

Syntax

C++

class OdGeEllipArc2d : public OdGeCurve2d;

Description

This class represents elliptical arcs and full ellipses in 2D space.

Remarks

The angle of a point on an ellipse is measured by projecting the point along a vector perpendicular to the major axis onto a circle whose center is the center of this ellipse and whose radius is the major radius of this ellipse. The angle between the major axis of this ellipse, and a vector from the center of this ellipse to the intersection point with the circle, measured counterclockwise, is the angle of this point on the ellipse.
