I am using 3DX Utility adaptor to export object content into V5 format with CATIAV5R18 downward compatibility option. The utility is running fine and generating the file for the first time when I run the activity. Running the same activity again is not generating the file. If I delete the generated file and run the activity again, it runs successfully and generates the file. The activity is generating the file as long as I remove the previously generated file. Is it the expected behavior? What needs to be done in order to generate the file for all runs?
