摘要
A method, apparatus and article of manufacture for mirroring a part model within a computer aided design computer system. A physical body, which is not directly accessible to the user is used for boundary representation of the non-mirrored part model, and a special mirror transformed instance of the physical body, called the logical body, is presented to the user. The logical body is a mirrored boundary representations of the same part model, and is not persistent to conserve computer resources. The invention uses face, edge, and vertex mapping to communicate between the two bodies, and uses matrix multiplication to perform the mirroring transformation.
