Michael,

Thanks for clearing things about control points. However I'm still confused with circular objects in MoI. When I display control points of a newly created circle primitive in MoI and Rhino, I see different results. I already read your posts about this and you are saying unlike Rhino MoI evaluates control points in a different way so that we can edit objects more smoothly.

Now please look at my example screenshot below. The shape on right is a rotated elliptical closed curve and left one is a perfect circle created from draw curve/circles.
It's obvious that right one is an ellipse, we can tell that just by looking at the shape. But let's just assume, we can't tell the difference just by looking. Then how do we know that it's a circle in MoI?





1. Both have 12 control points.
2. Both of their dimensions are 20x20mm
3. Both of them are closed curves.

So how do we know it's an ellipse or a circle in MoI?
Is there a built-in command or a script which circularizes any closed curve?

Thanks in advance.
