Abstract

Computer-based systems, methods, and computer-program products for automatically creating three dimensional geometric models are provided. The geometric models may be used to generate finite element models for computer modeling and loads testing. Automatically creating geometric models includes generating a surface curve based on surface and parameter information at all frame locations. Stringer points are automatically spaced on the first generated surface curve based on the parameter information. The stringer seed points are then propagated to the other frame curves based on parameter information. A stringer curve is automatically generated for each set of corresponding stringer points. The generated stringer curves are automatically projected onto the surface. All points, projected curves, lines and ribbon surfaces are named according to a naming convention established by the user to facilitate the automatic importation of the CAD elements into a FEM preprocessor program.
