STEP (Standard for the Exchange of Product data), otherwise known as ISO 10303, provides a mechanism to describe product data throughout the life cycle of a product, independent from any particular system.
STEP (Standard for the Exchange of Product data), otherwise known as ISO 10303, provides a mechanism that is capable of describing product data throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving.
Typically STEP can be used to exchange data between CAD, Computer-aided manufacturing, Computer-aided engineering, Product Data Management/EDM and other CAx systems. STEP is addressing product data from mechanical and electrical design, Geometric dimensioning and tolerancing, analysis and manufacturing, with additional information specific to various industries such as automotive, aerospace, building construction, ship, oil and gas, process plants and others.
