1. A computer implemented method for deforming the shape of a geometric model of a workpiece, said geometric model comprised of one or more material solids, said method comprising the steps of:

  • a) said computer constructing an original air solid, said original air solid positioned adjacent to and above said geometric model;

    b) said computer providing deformation parameters to a deformation means, said deformation parameters corresponding to manufacturing parameters for said workpiece;

    c) said computer constructing a modified air solid from said deformation parameters and said original air solid; and

    d) said computer performing one or more boolean set operations between said modified air solid, said original air solid and said geometric model, said boolean set operations performed according to said deformation parameters.
