The NX9 and NX10 STEP AP203 and AP214 translators will read AP242 step files and will process entities already supported by said AP203/AP214 translators. There is no NX capability yet to write out STEP files formatted as AP242 files. Now that AP242 has officially been published as an ISO standard we can start the investigation into expanding our AP242 support in NX11.
What exactly are you looking for?
NX11 has the ability to write to STEP AP242.
Is it possible to export NX model with 3D PMI to STEP AP 242 file with NX75? My customer would like to stay at NX75 but want to export STEP AP 242 file to help fully consume the 3D PMI in downstream applications.
