It's the same for an ellipse?
oops may be made with 2 arcs tangent ;)

Hi Michael,

Thanks i am looking forward to it

Funny that, I needed this a few days ago. Cool!
Thanks Michael.

Cheers

This is wonderful!

Hi Pilou,

> It's the same for an ellipse?

No - an ellipse does not tend to work in calculations similar to these because there tends to be an infinite variety of ellipses with slightly varying dual radius values that will match.

With a circle these situations have just a single circle solution, that makes it more possible to target that for an automatic solution.

Very useful addition....won't be long before im working in MoI and not Rhino :-))

Top job!

Don't you think someone,sooner or later will find a
mathematical solution

I would say 'Never say never'

Well, the problem is not that there is no solution, it is that there are a huge number of solutions of slightly varying ellipses.

There probably wouldn't be a good way for the algorithm to judge that one ellipse was better than any other, except for the case of having 2 equal radius values which is what the circle solution is...

To narrow down the huge number of solutions to a single one would probably require more steps like picking additional points or specifying a particular minor and major radius value. That is certainly possible to do, but it would make for a rather complex UI (kind of like a big "Ellipse control panel") for something that is just a rather obscure thing...

If building an ellipse in that specific manner is an important thing for you, you will probably need to get some specialized software that is focused a lot on ellipses and conic sections. Programs that are specialized in that will be able to devote a lot more detailed and complex UI to that problem.

Ok Michael, i am satisfied with
your answer
