The format of a STEP-file is defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure. [2] ISO 10303-21 defines the encoding mechanism for representing data conforming to a particular schema in the EXPRESS data modeling language specified in ISO 10303-11. A STEP-File is also called p21-File and STEP Physical File.
Most AICs are specializations in the geometric area. AICs did not exist back in 1994 when the first release of STEP got published. But when the 2nd generation of APs grows up it becomes clear that APs do not only share not only the IRs but also a lot of specializations. AICs are a big step towards AP interoperability.

The basis for STEP was the Product Data Exchange Specification (PDES), which was initiated during the mid-1980's and was submitted to ISO in 1988. [4] [5] The Product Data Exchange Specification (PDES) was a data definition effort intended to improve interoperability between manufacturing companies, and thereby improve productivity.
STEP - also known as ISO 10303-21 - has both advantages and disadvantages over IDF. If both MCAD and ECAD software support STEP, both programs can interchange more detailed models (at the cost of increased file size). Step models that are rendered correctly in the ECAD software can cause problems in the MCAD [citation needed].

“The history of 12-step came out of white, middle-class, Protestant people who want to be respectable,” said historian Nancy Campbell, a professor at Rensselaer Polytechnic Institute. “It offers a form of community and a form of belonging that is predicated upon you wanting to be normal, you wanting to be respectable, you wanting to have ...
