Unless you have a PDM system that is saving your iterations this is not possible. In a native filing system, NX does not save versions of the file, as Pro/E does.

good morning sir


thank u very much for ur support sir

Autodesk Inventor also can save previous versions. Unfortunately, NX does not.

Does your company do daily back-ups of all the UG directories? If so, you can ask your system support people to restore the old file but give it a new name.
