Anyone know the best way of creating an approx long axis for a closed curve which has a very close resemblance to an elipse but was not drawn using an elipse tool, its come in from photogrammetry so is a bit rough though I have cleaned it up with Fair. I am convinced the original shape is an elipse.
I have a custom CPlane for it but the shape is not horizontal.
If I can establish the axis that would be a good start and create an elipse to replace it.
Maybe its just a case of trial and error.
Google has just equations for establishing axes for actual elipses.
