1. A method for translating high order complex geometry from a computer aided design (CAD) model to a surface based combinatorial geometry format, comprising: Writing a list of trimmed surfaces from the CAD model, said trimmed surfaces being a bounded representation of a geometric surface in space; Generating lists of nodes that lie within the part or within any void spaces represented in the CAD model; Translating the trimmed surfaces into a list of analytic surfaces including bounding surfaces and ambiguity surfaces; and Formulating a well-posed zoning statement from the list of analytic surfaces and the list of nodes.
