1. An apparatus for determining a shape of a shim that can be inserted between a first body and a second body, the apparatus comprising:

  • a processing element for receiving a plurality of measured points that define a surface of the first body, said processing element also using an engineering surface and creating a vector passing through respective points of a group of the measured points and normal to the engineering surface, said processing element determining, for each point of the group, a distance between the engineering surface and a point that is local to the respective point in the group and is most outboard from the engineering surface, said processing element also constructing a plurality of new points with each new point associated with a respective point of the group and displaced the respective distance along the respective vector, said processing element further constructing a second surface of the second body from the plurality of new points so that the shape of the shim is defined between the plurality of measured points and the first surface.
