简单补充一下。/ {, W7 ^, q4 Y3 b

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.8 B# A& z8 P* B. w% P

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.# M& }5 C/ O9 ~/ w3 T5 R
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。

平时使用没发现什么区别,就是214好像文件会更小。 |
