AP schemas
APs, or Application Protocols, are the “top parts” of the STEP standard. Each covers a particular application or industry domain. See also: APs on Wikipedia
Official descriptions are in italics.
ap203
- Configuration controlled 3D designs of mechanical parts and assemblies
- One of the first schemas. Widely used, but also relatively primitive.
- New work should prefer AP242, as it offers a superset of ap203 modeling capabilities
ap203e2
- Second edition of ap203
- New work should prefer AP242, as it offers a superset of ap203 modeling capabilities
ap209
- Composite and metallic structural analysis and related design
ap210e2
- Electronic assembly, interconnect and packaging design
- Second edition of ap210
ap210e3
- Third edition of ap210
ap214e3
- Core data for automotive mechanical design processes
- Third edition of ap214
- New work should prefer AP242, as it offers a superset of ap203 modeling capabilities
ap219
- Dimensional inspection information exchange
ap227
- Plant spatial configuration
ap235
- Materials information for the design and verification of products
ap238
- Application interpreted model for computer numeric controllers
ap239
- Product life cycle support
ap240
- Process plans for machined products
ap242
- Managed model based 3d engineering
- combines and replaces the following previous APs in an upward compatible way:
- AP 201, Explicit draughting. Simple 2D drawing geometry related to a product. No association, no assembly hierarchy.
- AP 202, Associative draughting. 2D/3D drawing with association, but no product structure.
- AP 203, Configuration controlled 3D designs of mechanical parts and assemblies.
- AP 204, Mechanical design using boundary representation
- AP 214, Core data for automotive mechanical design processes
External Standards
These utilize parts of ISO10303 but are developed separately.
ISO15926
- Process plant lifecycle data
- Developed for oil & gas industry
ifc2x3
- Industry Foundation Classes - used in Building Information Modeling (BIM)
ifc4
- Newer version of Industry Foundation Classes
Other
pdm
- Product data management schema, embedded into many APs
STEPTools_merged_schema
- Created by STEPTools
- Modified due to a STEPcode parser error
- Not recommended for use, due to entity differences between the schemas that were merged.
- data corruption is likely
