STP files may include geometric dimensioning and tolerancing (GD&T) information to include allowances and tolerances read by CAM machines. STEP files also serve well for the detailed work of 3D printing and part machining. STP files also store part geometries mathematically, so CAM software can read the files to machine parts, which is a vital part of machining.Ĭompanies often use STEP or STP files to create pricing models and design molds for manufacturing parts. You can share, edit, and print 3D STEP files from various software programs. Use STEP files in architecture, design, manufacturing, and printing. The 2022 article, “ A Universal Method to Compare Parts from STEP Files,” published in the Journal of Intelligent Manufacturing, describes how important STEP files have become because they embed model-based definitions (MBD) that production lines use for setup and comparing parts. The format is both portable and accurate. The files store 3D modeling data and explanatory information in a plain-text ASCII format. Manufacturing, architecture, and mechanical industries use STEP files often. Use a STEP file for sharing 3D CAD files across platforms. Architecture, manufacturing, and 3D printing benefit from STEP files’ detail and flexibility.The ISO-10303-file standard provides portability throughout the design, development, review, and production phases.STEP files retain high data fidelity during the life of the file.STEP is the most popular 3D CAD and CAM file exchange format available today.The 2016 version of ISO 10303-21 supports external references, digital signatures, compression for archiving, and UTF-8 character encoding. You indicate line breaks with “\N” and page breaks with “\F”. However, files rendered in the 2016 version may include other digital signatures after the “END-ISO-10303-21 ” terminator. In a STEP file, the first characters in the first record are “ISO-10303-21 ” and the last record for files conforming to the 2002 version is “END-ISO-10303-21 ”. STEP files include plain-text information describing the object and supporting information about how to use it. Comments in STEP files are enclosed by “/ ” and “/” characters. STEP files encode data in the EXPRESS data modeling language, defined in ISO 10303-11. However, the code is complex, and users can corrupt files if they edit them incorrectly. STEP file data is saved in ASCII text, meaning users can open and change files in text editors. ▪ P-21, ISO part number that describes the file format, ISO 10303-21. The name of the originating standard for STEP files is ISO 10303-21:2016 Industrial automation systems and integration - Product data representation and exchange - Part 21: Implementation methods: Clear text encoding of the exchange structure. Some sources claim that STEP stands for “ Standard for the Exchange of Product Data.” STEP files also have other names: While they are the same file format, they have different extensions. Is there a difference between STEP and STP files? STEP files maintain accuracy and compatibility across teams and workflow, from design and development to production. Details saved in STEP files include descriptions of surfaces, trim curves, topology, and some color information. STP files read and save the whole 3D model body, including geometries and surfaces, so users can edit files in programs (other than those that created the file) and still retain resolution. Each program varies in how it interprets files, and diagnostic tools help to repair topology and geometry issues. For example, engineers may use one program for designing large objects and assemblies, but teams use another program to separate designs into parts or subassemblies for machining. STEP files exchange mechanical and architectural designs for real objects between different CAD software tools. STEP CAD models can represent complex geometries, making them well-suited to replicating physical objects in manufacturing processes. Use STEP files for 3D modeling and printing.ĭesigners and manufacturers use CAD to design and create objects such as machinery or parts, buildings, or other items. STEP files, also called STP files, are easy to share because users can open, view, and edit them in an assortment of (CAD) and computer-aided manufacturing (CAM) programs. We’ll cover why people use STEP files frequently and which programs you use to open, view, and convert STEP files.Ī STEP file is a commonly used standard computer-aided design (CAD) file format. We draw on our deep knowledge and experience in helping manufacturers with 3D files to explain the advantages and disadvantages of STEP files.
