How to "unerase cosmetic" in Creo 4.0 for weld display

[INENG]

I have weldment drawings that have had cosmetics erased. I wish to show welds in these views again. 

The "unerase cosmetic" option does not appear when I right click - even when on the Annotate tab. 

There doesn't seem to be a layer that has these cosmetics in it that I can show for the view. The welds are displayed as surfaces if that makes a difference. 

Any ideas?

I guess, you can't unerase cosmetic in drawing view. Best solution would be you can add a new view with default cosmetic and move all dimensions to the new view. This may works.
