A STEP-file is ASCII text with the format defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure. [2] ISO 10303-21 defines the encoding mechanism for representing data conforming to a particular schema in the EXPRESS data modeling language specified in ISO 10303-11. A STEP-File is also called p21-File and STEP Physical File.
ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information.It is an ASCII-based format. [1]: 59 Its official title is: Automation systems and integration — Product data representation and exchange.
The Open Inventor API is still commonly used for a wide range of scientific and engineering visualization systems around the world for the development of complex 3D application software. TGS was acquired by Mercury Computer Systems in 2004.
It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems.
IFC defines multiple file formats that may be used, supporting various encodings of the same underlying data. [7] IFC-SPF is a text format defined by ISO 10303-21 ("STEP-File"), where each line typically consists of a single object record, and having file extension ".ifc". This is the most widely used IFC format, having the advantage of compact ...
The first version of VRML was specified in November 1994. This version was specified from, and very closely resembled, the API and file format of the Open Inventor software component, originally developed by SGI. Version 2.0 development was guided by the ad hoc VRML Architecture Group (VAG). [4] A working draft was published in August 1996. [5]
The software can be licensed as a subscription or through pre-paid Flex Tokens (daily use, consumption-based). Autodesk Inventor Professional is also a part of a collection license Autodesk Product Design & Manufacturing Collection. Autodesk Inventor competes directly with SolidWorks, Solid Edge, and Creo.
The move was enabled by a clause in the 1990 contract between Autodesk and Spatial that made Autodesk a joint developer (with some restrictions) of the software with Spatial and provided an option to buy out of the contract to continue development of the source code on their own at a later date for $6.4 million.
