IEllipticArc.PutCoordsByAngle Method

Sets the center point, starting angle, signed central angle, angle of rotation, ratio of the minor axis to the major axis, and axes.

[Visual Basic .NET]
Public Sub PutCoordsByAngle ( _

Description

Creates an Elliptic Arc given the EllipseStd value, Center Point, From Angle, Central Angle, Rotation Angle, semi-Major Axis length, and Minor Axis to Major Axis Ratio.  If EllipseStd=TRUE, the From Angle is relative to the rotated semi-Major Axis rather than the X-Axis.

Remarks

This is the recommended way to create an arbitrary Elliptic Arc.  However, due to numeric accuracy limitations of computers and trigonometric functions, the From and To Points may be very slightly offset from the expected coordinates.  This is important to keep in mind when attempting to connect the endpoints to other segments.
