Origo of ellipse in EllipticalArc
Hi!
I need to calculate the origo of the ellipse that an EllipticalArc is drawn from. From the EllipticalArcTo geometry section i get. x1, y1  coordinates for starting point x2, y2  coordinates for control point x3, y3  coordinate for vertex point alpha  angle of the ellipses local coordinate system to the global coordinate system D  ratio between major and minor axis From these given values I need to calculate the global origo of the EllipticalArcs ellipse.

Me and a guy here where I work was successful in solving it using Maple...
Thanks anyway! "Paul Herber" wrote: On Mon, 15 Oct 2007 04:35:02 0700, Anders wrote: Hi! I need to calculate the origo of the ellipse that an EllipticalArc is drawn from.
