 AcDbEllipse::AcDbEllipse (AcGePoint3d&, AcGeVector3d&, AcGeVector3d&, double, double, double) |
This constructor is used to create an Ellipse using the values passed in. The center, unitNormal and majorAxis are used to calculate the start point. The majorAxis vector represents half the major axis of the ellipse (that is, from the center point to the start point of the ellipse) and is the zero angle for startAngle and endAngle. Positive angles are counter-clockwise when looking down the normal vector (that is, right-hand rule). A startAngle of 0 and endAngle of 2pi will produce a closed Ellipse.radiusRatio must be in the range 1E-6 to 1.0.The dot product of... more |
