STEP AP 242 is globally the declared backbone format for aerospace and automotive. With AP 242 there is a powerful standard for 3D Engineering in place, addressing not only well-known issues, but also support of e.g. composites and kinematics. The enhanced merger of AP 203 and AP 214, the standard for "managed model-based 3D engineering" is available as ISO 10303-242:2014 from ISO.An integral part of the standard is the smart XML representation of PDM-relevant information. To accompany the standard release prostep ivip will soon provide recommended practices for the implementation of AP 242 XML assembly structures which will complement the already available recommended practices of the CAx-IF.As far as VDA and prostep ivip are concerned, promoting wide use of the 1st edition of AP 242 in industry has top priority. This also includes maintaining the standard. From an organizational point of view, these activities are being performed within ISO as part of the initiative for the 2nd edition. VDA and prostep ivip will concentrate on the suitability of the current functional scope for use in industry and on maintenance. Maintenance of AP 242 requires close cooperation with the prostep ivip project groups CAx IF, JT Workflow Forum, JT Im-plementor Forum and the STEP Benchmark. The AP 242 project group will collect the re-quirements and feedback resulting from AP 242 implementation projects, check them against the standard, determine any resulting issues and develop solutions.
A Draft International Standard (DIS) for the 2nd edition of AP 242 was published and put to the vote internationally. The AP 242 Maintenance project has carefully reviewed this document, placing particular focus was on upward compatibility with the 1st edition. It is intended that the recommended practices provided by the association's implementor forums in the areas product and assembly structure, kinematics, configuration management and generated data remain valid. A second DIS document will be created to achieve this aim. International consensus on the content and approach was reached.
The AP 242 group will continue to collect the requirements and feedback from AP242 implementation projects, check them against the standard, determine any resulting issues and develop solutions in close cooperation with the prostep ivip project groups CAx IF, PDM IF, STEP Benchmark, JT Workflow Forum and JT Implementor Forum. AP 242 Edition 2 DIS-2 will again be the subject of an intensive review, and a German position paper will be drawn up. It is also intended that the requirements for a 3rd edition of the standard be collected and prepared. One topic in this context will be the description of PMI at assembly level.
The activities for 2019 will also include participation in the corresponding work groups of the ISO and the AP 242 project.
