A new tool is available to the design engineer to facilitate the design process. Solid Geometric Modeling is a relatively new form of Computer Aided Engineering. Solid Geometric Modeling can facilitate packaging, interference checking, visualization and visibility studies. By employing this tool in the early concept phase of design, many potential problems can be eliminated. This solid model can be refined to include more detail as the final design is determined. The model can then be passed to a CAD/CAM system for generation of drawings or N/C tapes, or to a Finite Element Pre-processing program where a finite element model can be built based on the geometry already created.
