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.

n4 f: U5 _$ o3 s# \6 d, T# bISO 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.9 f5 u& C, J& F- |& R b

以上两段,就不翻了,应该都看得懂。简单说,这两个标准都是来自iso 10303,就是当初为了不同CAD(CAE,CNC)系统之间数据交换制定的,所以,他的目标是产品的整个life cycle,大概就是PDM那套。当初肯定是非常先进的,现在嘛,有点难说。

; Q( J3 I! r) @* _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.9 f" _- _# z6 I4 M- W
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。6 N, d) I; `5 }6 O; D. a" c$ B# z
