tolerancing drawings attached with SW files

we want to start supplying drawings with cad models so less detailing of drawings is needed.  In a perfect world the part would come back the same as the cad model........  Does anyone have a generic tolerance they add to a drawing sheet to cover themselves when supplying a model?  THis way we dont have to spend hours dimensioning drawings

thanks
