Measure Radius of Elipse

[Guest]

A customer I've spoken with through the Tech Support line would like for a feature to exist that would automatically determine the radius of a non-symmetrical elliptical arc created by the Quarter Arc Tool.

That would be quite a feat... Does such a quality exist?

Given that it's an ellipse, I would have thought not, or, perhaps an infinite number of radii ;-)

but.....the NURBS interrogation function (is that what it's called?) might serve to give you the radius a a given point.

oop! just had a thought; perhaps they mean the location of the Foci? ..that could be a handy addition to ellipse set-outs.

If it was created by the Quarter Arc tool, the radii from the center to the endpoints would be half of the major and minor axes, which would be the ∆X & ∆Y values of the bounding box. Other values are harder to get.
