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.
Monolithic - All product structure is stored in a single JT file. PLMXML - An open XML-based file format, specified by Siemens Digital Industries Software. A PLMXML-structure could link to the model data in another file (an External Representation), or the data can be embedded within the Representation element in the XML file (an ...
Neutral file exchange uses an intermediary neutral format to translate data between CAD systems. This method starts from a pre-processor embedded in the original CAD system, which generates the neutral file from the originating CAD format. The target CAD system post-processes the neutral file and converts it into the target native format. [7]
Open Inventor, originally IRIS Inventor, is a C++ object-oriented retained mode 3D graphics toolkit designed by SGI to provide a higher layer of programming for OpenGL.Its main goals are better programmer convenience and efficiency.
While OPENSTEP and OSE were purchased by Apple, who effectively ended the commercial development of implementing OpenStep for other platforms, GNUstep is an ongoing open source project aiming to create a portable, free software implementation of the Cocoa/OPENSTEP libraries.
