简单补充一下。

STEP, the Standard for the Exchange of Product Model Data, is a comprehensive ISO standard (ISO 10303) that describes how to represent and exchange digital product information. 7 c# Q$ D& a" @

ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of industrial product data. Its official title is Industrial automation systems and integration - Product data representation and exchange, and it is also known as STEP or the Standard for the Exchange of Product model data. The standard's objective is to provide 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.

至于两者的区别,也很好解释。! U- D6 K0 F/ D# y6 ?- ~* P) V

实际上两者区别不是很大,AP-203 and AP-214 use the same definitions for three dimensional geometry, assembly data and basic product information./ i7 Z2 y0 T! k: r0 o
只是据说美国人用203的多,欧洲人用214的多。但203用的应该更广一些。$ S8 }+ e6 B# K! }2 O
