When UGII_GENERATE_MULTI_CAD_JT=1 is set, there is no JT file being created from NX when mergeSolids is set to true.
Solution
Please check the tessUG.config file for this setting: mergeSolids
Parameter mergeSolids needs to be set to false if environment variable UGII_GENERATE_MULTI_CAD_JT=1 exists.
