Intersection

Learning targets

• Use Boolean operation to intersect two objects

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

      BooleanOperation {

        Operator = Intersection
        A { 
          Circle {
            Radius = 6
            GlobalPosition = [-4.0 0.0]
            RefineAll = 2
          }
        }
        
        B {
          Circle {
            Radius = 4
            GlobalPosition = [1.75 0.0]
            RefineAll = 2
          }
        }
      }
    }  
  }
  

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:
