    116 /// \brief
    117 /// The FdoIEllipticalArcSegment class represets an Elliptical Arc Segment
    118 /// geometry type. EllipticalArcSegment can describe portions of, or a full
    119 /// ellipse. If describing a full ellipse, the start and end points are identical
    120 /// and the mid-point is the diametrically opposite point on the ellipse.
    121 ///
    122 /// \remarks
    123 /// Two foci were specified as opposed to major/minor axes so that the
    124 /// API can derive this class from ArcSegmentAbstract and CurveSegmentAbstract,
    125 /// thus reusing the concepts of start/mid/end points as defined in the base
    126 /// classes. In this manner the API can maintain a common look/feel when defining
    127 /// arc types. The expectation is that a Geometry API utility method will be
    128 /// provided that will allow conversion to major/minor axis.
    129 ///
    130 /// The semimajor axis and the semiminor axis are one half of the major and minor
    131 /// diameters, respectively. These are sometimes called the major and minor semi-axes,
    132 /// the major and minor semiaxes,or major radius and minor radius.
    133 ///
    134 /// The foci of the ellipse are two special points on the ellipse's major
    135 /// axis and are equidistant from the center point. The sum of the distances from any
    136 /// point on the ellipse to those two foci is constant and equal to the major
    137 /// diameter. Each of these two points is called a focus of the ellipse.

     111Two foci were specified as opposed to major/minor axes so that the API can derive this class from !ArcSegmentAbstract and !CurveSegmentAbstract, thus reusing the concepts of start/mid/end points as defined in the base classes. In this manner the API can maintain a common look/feel when defining arc types. The expectation is that a Geometry API utility method will be provided that will allow conversion to major/minor axis.

     113The semimajor axis and the semiminor axis are one half of the major and minor diameters, respectively. These are sometimes called the major and minor semi-axes, the major and minor semiaxes,or major radius and minor radius.
     114
     115The foci of the ellipse are two special points on the ellipse's major axis and are equidistant from the center point. The sum of the distances from any point on the ellipse to those two foci is constant and equal to the major diameter. Each of these two points is called a focus of the ellipse.
