I need to remove the model creation date from a number of parts - these are parts that I raised mainly as items for my SWX part library whilst running my consultancy but now am going to be using them and I forsee a problem with history when I commence a new venture with a rival company. I really do not want to remodel a large number of parts so deleting/ modifying the model creation date would be far more preferable. Is there any way that this can be achieved? Any help as always gratefully received. - Thank you.
