Buil in an automatic save before sketcher or imbeded sketcher is opened.
This is to prevent CREO bombing out when sketcher looses control and a lot of work is lost.
I see a problem with this. Saving a part also deletes undo. Maybe as a hidden option, but I wouldn't like that as a general function.
Some level of intelligent autosave might be nice, but again, outside of the workstream where these files are temp files only to be recovered when needed.
I make a lot of specials that are modifcations of the standards, but I do not save them nor do I want to. This would complicate things quite a bit.
