Good evening
I would need with a simple sketch that I don't understand. I don't understand how to put the radius of 20, because when I want to put the radius 20 it doesn't mean since the length and width are already dimensioned. If someone could try to make this sketch and explain to me how they do it.

Hello
It's true that the shape is reminiscent of the ellipse, but probably drawn by 4 tending arcs

Hello

I confirm my VDD, it is indeed 4 arcs of a circle in vertical and horizontal symmetry.
I did the test with an ellipse and it is slightly more domed than the arc version, which corresponds to an R22 or R22.5mm.
