    Abstract

    A FORTRAN program has been developed to fit smooth surfaces13; to the component parts of an arbitrary aircraft configuration or any three-dimensional geometry. The basic surface element used for this fit is a bi-cubic surface patch. Once the geometry has been replaced by a set of patch equations, various kinds of calculations which require a three-dimensional mathematical description of the surface can be performed easily. The second part of the code generates orthographic views of the given geometry on a calcomp drum plotter or on a Tektronix screen.13;
