IGES , STEP is Cad File Format which allows you to open 3D Model in any Software and Edit it. IGES and STEP are the widely used neutral CAD formats and accepted in all software. In IGES the output is in surfaces while STEP file keeps the assembly hierarchy and output is a mixture of solids/volumes and surfaces (only solids in most of the cases).
The IGES and STEP formats serve as neutral data formats to transfer the design to a dissimilar system. Translators developed to the IGES and STEP standards are used to export a design into an IGES and STEP files for exchange and for importing the IGES and STEP files into the destination system
What is STP/ STEP file Format
STP is a file extension for a 3-D graphic file used by CAD software. STP stands for STandard for the Exchange of Product model data. STP files are used to store 3D image data in an ASCII format, following the standards defined in ISO 10303-21 : Clear Text Encoding of the Exchange Structure.
The step file extension is used for 3D files created in STEP (Standard for the Exchange of Product Data) format.
STEP is an ISO standard for the computer-interpretable representation and exchange of industrial product data. Typically STEP can be used to exchange data between CAD, Computer-aided manufacturing, Computer-aided engineering, Product Data Management/EDM and other CAx systems.
STEP is addressing product data from mechanical and electrical design, Geometric dimensioning and tolerancing, analysis and manufacturing, with additional information specific to various industries such as automotive, aerospace, building construction, ship, oil and gas, process plants and others.
What Is iges Stands For ?
Initial Graphics Exchange Specification (IGES ) is a neutral file format designed to transfer 2D and 3D drawing data between dissimilar CAD systems. The IGES standard defines two file formats: fixed-length ASCII, which stores information in 80-character records, and compressed ASCII. The IGESIMPORT and IGESEXPORT commands support only the fixed-length format.
IGES was the first standard exchange format developed to address the need to communicate product definition data among different CAD/CAM/CAE systems . The early versions of IGES implicitly aimed at the CAD/CAM systems of the 1970s and early 1980s. Recent versions have extended the types of data to be exchanged. Version 2.0 of IGES in July 1982 was approved to support the exchange of finite-element data and printed circuitboard data. Along with Version 2.0 was a general committee towards ensuring that IGES can handle the graphic representations for all products. Version 3.0 later enhanced the capabilities of user-defined Macros that are essential to exchange the standard part libraries. Version 4.0 supports the CSG tree of a solid. For solid modeling with boundary representation, IGES version 5.0 was produced in 1991.
