IGES - Wikipedia, the free encyclopedia. Logo of the IGES Project from NISTThe Initial Graphics Exchange Specification (IGES) (pronounced eye- jess) is a vendor- neutral file format that allows the digital exchange of information among computer- aided design (CAD) systems.

The official title of IGES is Digital Representation for Communication of Product Definition Data, first published in January, 1. U. S. National Bureau of Standards as NBSIR 8. Many documents (like early versions of the Defense Standards MIL- PRF- 2. MIL- STD- 1. 84. 0[2]) referred to it as ASME Y1. M, the designation of the ANSI committee that approved IGES Version 1. Using IGES, a CAD user can exchange product data models in the form of circuit diagrams, wireframe, freeform surface or solid modelingrepresentations. Applications supported by IGES include traditional engineering drawings, models for analysis, and other manufacturing functions.

History[edit]IGES was an initiative of the United States Air Force (USAF) Integrated Computer Aided Manufacturing (ICAM) project (1. ICAM sought to develop procedures (IDEF) processes (Group Technology) and software (CAD/CAM) that would integrate all operations in Aerospace manufacturing and thus greatly reduce costs. Earlier the USAF Manufacturing Technology Program had funded the Automatically Programmed Tools (APT) language for programming Numerically Controlled (NC) machine tools. To close the data gap between parts design and manufacturing, one of the ICAM goals was to develop CAD software that would automatically generate numerical control programs for the very complex Computer Numerically Controlled (CNC) machine tools used throughout the Aerospace industry. A serious issue was the incompatibility of data produced by the many CAD systems in use at the time.

USAF/ICAM called a meeting at the National Bureau of Standards (now known as National Institute of Standards and Technology or NIST) in 1. Boeing offered to sell its CAD translation software to USAF for one USA dollar. USAF accepted this offer and contracted NIST to bring together a group of users and vendors, including Boeing, General Electric, Xerox, Computervision, Applicon and others to further develop and test this software. Though it was the practice to begin the name of ICAM developments with the word integrated (for example the IDEFs) believing that there would be rapid development of graphical exchange software, USAF decided that the IGES would be the Initial Graphics Exchange Specification not the Integrated Graphics Exchange Specification. Since 1. 98. 8, the Do.

D has required that all digitalproduct and manufacturing information (PMI) for weapons systems contracts (the engineering drawings, circuit diagrams, etc.) be delivered in electronic form such as IGES format. As a consequence, CAx software vendors who want to market their products to Do. D subcontractors and their partners needed to support the import (reading) and export (writing) of IGES format files. An ANSI standard since 1. IGES has been used in the automotive, aerospace, and shipbuilding industries.

It has been used for weapons systems from Trident missileguidance systems to entire aircraft carriers. These part models may have to be used years after the vendor of the original design system has gone out of business. IGES files provide a way to access this data decades from now. Today, plugin viewers for Web browsers allow IGES files created 2. After the initial release of STEP (ISO 1. IGES declined, and Version 5.

File format[edit]An IGES file is composed of 8. ASCII records, a record length derived from the punched card era. Text strings are represented in "Hollerith" format, the number of characters in the string, followed by the letter "H", followed by the text string, e. HSLOT" (this is the text string format used in early versions of the Fortran language). Early IGES translators had problems with IBMmainframe computers because the mainframes used EBCDIC encoding for text, and some EBCDIC- ASCII translators would either substitute the wrong character, or improperly set the parity bit, causing a misread.

Here is a very small IGES file from 1. POINT (Type 1. 16), two CIRCULAR ARC (Type 1. LINE (Type 1. 10) entities. It represents a slot, with the points at the centers of the two half- circles that form the ends of the slot, and the two lines that form the sides. S 1. 1. H,,1. H; ,4. HSLOT,3. 7H$1$DUA2: [IGESLIB.

Foreign Language Support[edit]. IGES file that demonstrates Font Code 2.

Japan Automobile Manufacturers Association (JAMA) to exchange part models with their American and European partners without loss of the Kanji text. The current version of IGES does not support Unicode 1. Arabic and other scripts (like Thai) cannot be represented.[8]A Recursive Standard[edit]One of the unique features of the IGES standard is that it was the first ANSI Standard to be documented using itself. Since Version 4. 0, all of the technical illustrations for the printed version of the standard have been generated from IGES files. The electronic publishing system (La.

Te. X) integrates raster images generated from IGES files into the Post. Script sent to the laser jetcomputer printer, so text and images are printed on the same page for subsequent use as camera- ready copy for commercial publication. Beginning with IGES Version 5.

Family Tables are collections of parts (or assemblies or features) that are essentially similar, but deviate slightly in one or two aspects, such as size or detail features. For example, wood screws come in various sizes, but they all look alike and perform the same function. Thus, it is useful to think of them as a family of parts. Parts in Family Tables are also known as table- driven parts. Using Family Tables, you can.

Create and store large numbers of objects simply and compactly. Save time and effort by standardizing part generation. Generate variations of a part from one part file without having to re- create and generate each one.

Create slight variations in parts without having to use relations to change the model. Create a table of parts that can be saved to a print file and included in part catalogs. Family Tables promote the use of standardized components. They let you represent your actual part inventory in Pro. E/Creo. Moreover, families make it easy to interchange parts and subassemblies in an assembly, because instances from the same family are automatically interchangeable with each other. Family Table Structure.

Family Tables are essentially spreadsheets, consisting of columns and rows. They consist of the following three components. The base object (generic object or generic) on which all members of the family are based. Dimensions and parameters, feature numbers, user- defined feature names, and assembly member names that are selected to be table- driven (hereafter referred to as items).

Names of all family members (instances) created by the table and the corresponding values for each of the table- driven items. Rows contain instances of parts and their corresponding values; columns are used for items. The column headings include the instance name, and the names of all of the dimensions, parameters, features, members, and groups that were selected for the table. Dimensions are listed by name (for example, d. Parameters are listed by name (dim symbol).

Features are listed by feature number (for example F1. The generic model is in the first row in the table.

The table entries belonging to the generic can be changed only by modifying the actual part, suppressing, or resuming features; you cannot change the generic model by editing its entries in the Family Tables. Note: Family Table names are not case- sensitive. Therefore, any subsequent references to inserted names show them in uppercase letters. For each instance, you can define whether a feature, parameter, or assembly name is used in the instance either by indicating whether it is present in the instance (Y or N) or by providing a numeric value (in the case of a dimension).

All dimension cells must have a value, either a number or asterisk (*) to use the generic's value. All aspects of the generic model that are not included in the Family Table automatically occur in each instance. For example, if the generic model has a parameter called Material with a value Steel, all instances will have the same parameter and value. You can scroll horizontally through a Family Table to see additional information. The Instance Name column remains visible as you scroll.

Family Table functionality varies with your Pro. E/Creo module licenses.
