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.
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.
STEP (ISO 10303 – STandard for the Exchange of Product model data) The work with the ISO 10303 standard was initiated in 1984 and initially published in 1994, with the objective to standardize the exchange of product data between PLM systems. It is a very comprehensive set of specifications covering many different product types and many life ...
ISO 10303-21: Data exchange form of STEP with an ASCII structure; ISO 10303-22: Standard data access interface, part of the implementation methods of STEP; ISO 10303-28: STEP-XML specifies the use of the Extensible Markup Language (XML) to represent EXPRESS schema; ISO 13584-24: The logical model of PLIB is specified in EXPRESS; ISO 13399: ISO ...
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. The combined result has been standardized as ISO 10303-238 [2] (also known as AP238).
Part 216 - Ship moulded forms; Part 218 - Ship structures; Part 219 - Dimensional inspection information exchange; Part 221 - Functional data and their schematic representation for process plant; Part 223 - Exchange of design and manufacturing product information for cast parts, currently on CD level
The STEP ISO 10303 Application modules define common building blocks to create modular Application Protocols (AP) within ISO 10303. Higher-level modules are built up from lower-level modules. The modules on the lowest level are wrappers of concepts, defined in the Integrated Resources (IR) or Application Integrated Constructs (AIC). Modules on ...
STEP-XML specifies the use of the Extensible Markup Language to represent EXPRESS schema (ISO 10303-11) and the data that is governed by those EXPRESS schema. It is an alternative method to STEP-File for the exchange of data according to ISO 10303. The following specifications are within the scope of ISO 10303-28:
