I've done exactly what you both said, first I've created the ellipses and the circle with a line thickness of 2cm and then converted them to shape. After that, centered all (after rotating the two ellipses 45° and -45° respectively) and CTRL-5 to intersect. Done that I've united again the pieces so to build your design an finished adding the line width required.[/QUOTE]Thank you Marco, this is exactly what I did.
I have found that if you do not have the rotation of the shapes are zero or so other corner angle, you get extra jaggies.
In this case, I got round it by cloning the cutout circle rotating it 180° (as it is rotationally symmetrical) and Adding Shapes.
Full marks.
