Part 101 - Draughting Part 104 - Finite element analysis Part 105 - Kinematics Part 107 - Finite element analysis definition relationships Part 108 - Parameterization and constraints for explicit geometric product models Part 109 - STEP assembly model for products Part 110 - Computational fluid dynamics data Part 111 - Elements for the procedural modelling of solid shapes Part 112 - Standard modelling commands for the procedural exchange of 2D CAD models 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. Part 204 - Mechanical design using boundary representation Part 207 - Sheet metal die planning and design Part 209 - Composite and metallic structural analysis and related design Part 210 - Electronic assembly, interconnect and packaging design. The most complex and sophisticated STEP AP. Part 212 - Electrotechnical design and installation. Designed as a complement for AP214, but not fully harmonized with it.
