Loo Monford. What you say that you want to open a pro-wf3 file in wf2 version i would say that it's not possible becuse in pro-e it don't allow you to open any file of higher version(wf3) in lower version(wf2)but if you despertely needed then you can make a IGS file in (WF3)& then open it in wf2 i think it may work.
