< its not corect because the parts of maiandros u have make its not have the same diastance.i
So it's for that I made the little construction above! :)
You must draw by hand 1/4 of the oval motif and then make some mirror symmetry :)
As you see on your model curves up and down are curved!
And even some down curved lines have not the same measure on the angle of the oval than on the side!
You must draw by hand one by one with some helpers lines like in my little construction :)
It's not a speedy work if you want this exact model :)
