ABSTRACT:
One implementation provides a method for processing a first representation of a geometry of a component that is stored in a computer file. In this implementation, the method includes analyzing the first representation of the geometry of the component, and, upon analysis, generating a second, non-invertible representation of the geometry of the component from the first representation, the second representation being at least partially independent of a rotation or a translation of the component in space.
