is there any way to export all the bodies in a step file to individual part files?
thanks in advance.
STEP files can contain assembly structure, it depends on the options used when exporting the file. If the STEP file contains assembly structure, NX will create a new part file for each component if the "flatten assembly" import option is turned off.
If the assembly structure was not preserved in the STEP file, you will end up with a bunch of bodies in a single part file. It is possible for a journal to export each body to a new file; you would need to define a naming scheme before attempting to export.
