Application Protocol
The 'APs' utilize the lower-level information of integrated resources in well defined combinations and configurations to represent a particular data model of an engineering or technical application.- Part 201 - Explicit draughting. Simple 2D drawing geometry related to a product. No association, no assembly hierarchy. Practically a subset of AP202 and 214.
- Part 202 - Associative draughting. 2D/3D drawing with association, but no product structure. Practically a subset of AP214.
- Part 203: Configuration controlled 3D designs of mechanical parts and assemblies. Mainly used for 3D design and product structure. A subset of AP214 but most widely used.

ATS - Abstract test suite
An ATS is a formal description on how to test STEP implementations for conformance. They contain a test plan for postprocessors (exporting STEP data) and preprocessors (importing STEP data). The structure of an ATS is defined in part 34.The original plan of STEP was to have for every AP 2xx a corresponding ATS 3xx, but only a few were finally realized till today.
AIC - Application interpreted constructs
AICs are specializations of the integrated application and generic resources. This is done by subtyping interfaced entities and adding further constraints and rules. No new stand-alone entities are created and no new explicit attributes are added. 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.- Part 501 - Edge-based wireframe
