    摘要： A computer aided design system comprises a processor which has access to different instruction memories. In a 2D mode of operation, the processor executes only the information stored in a 2D instruction memory, said instructions only referring to 2D geometry. If the processor receives a command related to 3D geometry, control is transferred to a transformation instruction memory which converts 2D geometry into 3D geometry and performs a topology check. Then (or upon entering of a 3D command) control is transferred to a 3D instruction memory which performs the necessary steps in 3D. The invention also relates to the method of system performance which allows easier and faster processing of geometric information.
