Редактирование: IGES

IGES (Initial Graphics Exchange Specification) – a neutral (not original for any commercial system) file format for data exchange between various [[CAD]] systems. The first format specification was developed in 1980 owning to the efforts of Boeing and General Electric, and in 1981 it was accepted as [[ANSI]] standard. The first version was designed mainly for drawing exchange between drawing automation systems. 2.0 version supported data for the finite elements analysis and specific elements of  p-c boards. 3.0 version supported user macro commands, and 4.0 – solid bodies in the form of CSG trees, while 5.0 supported the Brep structure. The standard supports three content- and structurally equivalent formats of IGES-files – text ([[ASCII]]) with fixed-length lines, compressed [[ASCII]] and binary.
