简单补充一下。- c; g+ _0 e; X: h+ W5 P

6 G3 K8 J& W* X. y' C7 m7 q$ b 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.

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。: w% r6 F1 z. ^# h7 O

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 n- ^' Z7 A2 }7 p
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。7 ^5 ~3 Y4 g8 Q7 g: ^% l

平时使用没发现什么区别,就是214好像文件会更小。 |
