User restarted NX, and is still getting the WARNING 2556 error/warning.
I started a new NX ssession, and looked in the log file, and see no mention of "LegacyHeavyweightSectionViews = true", would it show here?
Looks like there may be an additional setting you need to add to the tessUG.config file:
NX to JT translator writes the section view to the JT file only when you:
Generate a JT file using File tab→Export→JT or command line application ugtopv invoked with
LegacyHeavyweightSectionViews = true and
mergeSolids = true in the JT configuration file.
We had a similar problem but cleared it by deleting the default.log file from the item folder in the temp folder. This is covered in PR8340533 on the GTAC solution centre.
