STEP-file is a widely used [1] data exchange form of STEP.ISO 10303 can represent 3D objects in computer-aided design (CAD) and related information. A STEP-file is ASCII text with the format defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure.
It is an ASCII-based format. [1]: 59 Its official title is: Automation systems and integration — Product data representation and exchange. It is known informally as "STEP", which stands for "Standard for the Exchange of Product model data". ISO 10303 can represent 3D objects in Computer-aided design (CAD) and related information.
This file format considers the product definition as a file of entities, with each entity being represented in an application-independent format. [3] After the initial release of STEP (ISO 10303) in 1994, interest in further development of IGES declined, and Version 5.3 (1996) was the last published standard.
An IGES file is composed of 80-character 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.g., "4HSLOT" (this is the text string format used in early versions of the Fortran language).
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.

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 size yet readable text. IFC-XML is an XML format defined by ISO 10303-28 ("STEP-XML"), having file extension ...
The STEP (Standard for the Exchange of Product Model Data) file format, also known as ISO 10303, is a standardized 3D model format in the field of engineering. [7] STEP files are used to describe the complete 3D geometry of an object in a way that is independent of any specific CAD (Computer-Aided Design) system, making them highly ...
