Paper Abstract

Considerable strides have been made in the field of automatic transfer of CAD/CAM data in the last decade. Success in the use of the Initial Graphics Exchange Standard (IGES) for the transfer of optomechanical data has been reported at regular intervals since 1986. Nevertheless IGES has demonstrated some weaknesses with respect to mechanical drafting entities and appears to suffer from excessively large file structures yielding inadequate data precision for the representation of optical systems. Recognizing these voids in the representation of optical models a task group under the International Organization for Standardization (ISO) has undertaken the development of a completely new standard for the transfer of optical model data. NODIF as it is called represents a very ambitious effort to transfer optical data without any reliance on traditional graphical representation. In so doing it is significantly different from IGES and thus should not be regarded as a competing standard. Rather NODIF promises to compliment IGES as a subset of the STEP standard. L
