This example intersects two circles by means of the Boolean intersection operator to form a lens like object.

Shape manipulating operations such as corner rounding can be applied to the resulting shape, e.g.:

BooleanOperation {
  A {
    ...
  }
  B {
    ...
  }
  CornerRounding {
    Radius = 0.5
    MaxAngle = 140
    NPoints = 5
  }
}

which yields the following geometry:
