Replace a part in a drawing with an assembly. Example: A part has threaded holes and is completely dimensioned. The threaded holes need to be changed to a Helicoil inserts. Rather than having to create a new drawing from scratch, have the functionality to replace the part with the new assembly. The assembly is exactly the same as the part, with the exception of the new tapped holes and the Helicoil inserts, which are in the same position as the original tapped holes.
