Closing Elliptical Arc

Hi,

Recently, a question about to draw the close ellipse on the Elliptical Arc was posted.
It was not easy question. I could not answerd.
So, I've studied again in deep, and made one solution.
The 3-equation can be easily solved, when I introduced a dummy
coordinate system.

You can change the elliptical arc by moving the control point and
change the direction and length of the control lever.

On the first page of Visio drawing the result is shown,
and on the second page the description how to solve the
equations are written.

In Octover, 2007 Anders has posted a question about same problem at,
http://www.officefrustration.com/showthread.php?t=748811
I think Anders has solved the problem.
I would like to hear how you solved.

Thanks for resolve this question. JuneTheSecond, thank you very much. You really safe my time. Thank you again.

JuneTheSecond:
If VBA is allowed, my shape "Ellipse by 5 Points" is easy way to draw closed ellipse.

Hi,

The first EllipticalArcTo.vsd is enhanced with VBA so as you can fit closed ellipse to any Elliptical arc.

Jerry:
It's a very good sample for Elliptical Arc
