The basis for STEP was the Product Data Exchange Specification (PDES), which was initiated during the mid-1980's and was submitted to ISO in 1988. [4] [5] The Product Data Exchange Specification (PDES) was a data definition effort intended to improve interoperability between manufacturing companies, and thereby improve productivity.
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. Due to its ASCII structure, a STEP-file is easy to read, with typically one instance per line. The format of a STEP-file is defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure. [2]
The typical work-around when sharing files with an outside organization is to export the file using two open-file-type standards: IGES, which was released in 1980 by the National Institute of Standards and Technology (then known as the National Bureau of Standards), and STEP, released in 1984/85.
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).

IGES was not, then, suitable. Another complication was the coexistence of, then, two major representations, CSG and Boundary Representation, although use of CSG in commercial systems started to decline later.
