The "save as" performed by Creo M070 doesn't maintain the name of the original file, but its Name is the file number. I can't understand this behaviour, also because,in Windchill it works different and, in my opinion, in the right way. M030 version works correctly and I don't understand why it has been changed.
In this "new" behaviour, it is the same in WF, and for me M030 was one of the best improvements, it is necessary to change the name of all duplicated parts (or do it in Windchill).
The proposal is to come back to the behaviour of M030 or, at least, give the possibility to choose the old system (WF and M060 and following) or new system (as M030).
