A method and system are disclosed for handling logical-to-physical mapping and increasing the amount of mapping table information that may be stored in a cache in volatile memory. More specifically, this invention relates to creating a new net locating scheme for a body-in-white to direct associated tooling to create net attachment features on a rigid body frame with respect to a new net locating scheme so that components may be attached to an automotive body at a net location eliminating the need for any slip plane attachment techniques. The lower of the two portions is an input shaft. Aesthetic refinement techniques enable the creation of splines with precise inflection points.
