I opened my top level assembly (over 4000 parts) in Design Review Mode but use the "selective open" to display part of the top level assembly. I would like to create a new assembly for just the displayed parts but when I do that I get lots of other parts that were not displayed come in to the new assembly. Is there a macro that I can use to accomplish this task? I would only like to add the parts that were displayed from the Design Review Open to form the new assembly. Thanks for any help.
