Export in STEP Format from Windchill

[MH_11857812]

I am using Windchill PDMLink Release 11.1 and Datecode with CPS M020 CPS30

Dear Support Assistant Team!

I tried to make this sample code work: https://support.ptc.com/help/windchill/r13.0.0.0/en/index.html#page/Windchill_Help_Center/customization/WCCG_PLMServices_STEPPLMExportImport.html, but at the end I am not able to use it. I tried to export into STEP FORMAT AP242 with implementation method both 21 and 28 for OptionSets, Parts, CAD object, but all of them failed with "Problem in export/import process. Nested exception is: java.lang.NullPointerException". Can you help us to make this code work?
Thank you in advance!
Kind regards,
Martin Herbert

Martin,

If you are still facing this issue, can you please provide your custom source code and Windchill Method Server log snippet containing the NullPointerException with the stack trace?
