About this oval
I want to divide the curve ellipse AB in 5 egal parts
I am not sure if this construction is right?
It will be fine if a function Divide a curve exist in Moi :)
There is one inside the helpers but it's just for straight lines :) (used here for draw the circles)
Second image seems better :)
I have used the array / curve with AB as line and AC as Path
So circle's method was false
And now you can draw a perfect Greca motif :)

Ps can we use Array / curve as trusty tool for divide any curves?
